Hi,
I've been able to install current from netboot on a 8MB sparc IPX, the only
requirement is to use a smaller kernel than GENERIC or GENERIC_SCSI3.
GENERIC doesn't load, it fails with:
Booting netbsd
Cannot load netbsd: error=27
(27 is EFBIG)

I don't think the problem is the amount of RAM, but it's probably the
fact that it's 2 segments of 4MB with a hole between them.
The kernel I used is just GENERIC with sun4m-specific things commented out,
no RASTERCONSOLE, no KTRACE/SYSTRACE, no pseudo-filesystems (they can be
loaded as LKM), and no network protocols others than INET and INET6.
There may be a few more things that could be removed, like sbus cards known
to work only on sun4m systems. This kernel should work for all sun4 and sun4c
systems, and is 2762499 bytes (vs 3472644).

Is it worth adding to the list of standard kernels and distribution,
or do we assume peoples with low memory machines will be able to cross-compile
their own kernel ?

# GENERIC machine description file
# 
# This machine description file is used to generate the default NetBSD
# kernel.  The generic kernel does not include all options, subsystems
# and device drivers, but should be useful for most applications.
#
# The machine description file can be customised for your specific
# machine to reduce the kernel size and improve its performance.
#
# For further information on compiling NetBSD kernels, see the config(8)
# man page.
#
# For further information on hardware support for this architecture, see
# the intro(4) man page.  For further information about kernel options
# for this architecture, see the options(4) man page.  For an explanation
# of each device driver in this file see the section 4 man page for the
# device.

## System kernel configuration.  See options(4) for more detail.


# Options for variants of the Sun SPARC architecure.
# We currently support three architecture types; at least one is required.
options 	SUN4		# sun4/100, sun4/200, sun4/300
options 	SUN4C		# sun4c - SS1, 1+, 2, ELC, SLC, IPC, IPX, etc.
#options 	SUN4M		# sun4m - SS10, SS20, Classic, etc.

options 	SUN4_MMU3L	# sun4/400 3-level MMU

## System options specific to the sparc machine type

# Blink the power LED on some machines to indicate the system load.
#options 	BLINK

## Use a faster console than the PROM's slow drawing routines.  Not needed
## for headless (no framebuffer) machines.
#options 	RASTERCONSOLE		# fast rasterop console
#options 	FONT_GALLANT12x22	# the console font
#options 	FONT_BOLD8x16		# a somewhat smaller font
## default console colors: black-on-white; this can be changed
## using the following two options.
#options 	RASTERCONSOLE_FGCOL=WSCOL_BLACK
#options 	RASTERCONSOLE_BGCOL=WSCOL_WHITE

#### System options that are the same for all ports

## Root device configuration: change the ?'s if you are going to use a
## nonstandard root partition (other than where the kernel is booted from)
## and/or nonstandard root type (not ffs or nfs).  Normally this can be
## automagically determined at boot time.

config		netbsd	root on ? type ?

## System call tracing (see ktrace(1)).
#options 	KTRACE
#options 	SYSTRACE	# system call vetting via systrace(1)

## Collect statistics on kernel malloc's and free's.  This does have a
## significant performance hit on slower machines, so it is intended for
## diagnostic use only.
#options 	KMEMSTATS

## System V compatible IPC subsystem.  (msgctl(2), semctl(2), and shmctl(2))
options 	SYSVMSG		# System V message queues
options 	SYSVSEM		# System V semaphores
#options 	SEMMNI=10	# number of semaphore identifiers
#options 	SEMMNS=60	# number of semaphores in system
#options 	SEMUME=10	# max number of undo entries per process
#options 	SEMMNU=30	# number of undo structures in system
options 	SYSVSHM		# System V shared memory
#options 	SHMMAXPGS=1024	# 1024 pages is the default

## Loadable kernel module support; still under development.
options 	LKM

options 	USERCONF	# userconf(4) support
#options	PIPE_SOCKETPAIR	# smaller, but slower pipe(2)

# Enable experimental buffer queue strategy for better responsiveness under 
# high disk I/O load. Use it with caution - it's not proven to be stable yet.
#options 	NEW_BUFQ_STRATEGY

## NFS boot options; tries DHCP/BOOTP then BOOTPARAM
options 	NFS_BOOT_BOOTPARAM
#options 	NFS_BOOT_BOOTP
options 	NFS_BOOT_DHCP

#### Debugging options

## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
## serial console break or keyboard reset, where the PROM would normally
## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.
#options 	DDB			# kernel dynamic debugger
#options 	DDB_HISTORY_SIZE=100	# enable history editing in DDB
#options 	DDB_ONPANIC=1		# see also sysctl(8): `ddb.onpanic'

## You may also use gdb, on another computer connected to this machine over
## a serial port.  Both KGDB_DEV and KGDB_DEVRATE should be specified;
## KGDB_DEV is a dev_t encoded device number of the serial port to use, where
## the minor device number encodes the PROM enumeration of the serial ports,
## i.e.:
## 0xc00 = ttya, 0xc01 = ttyb, 0xc02 = ttyc, 0xc03 = ttyd.
## (Note: ttyc and ttyd are available only on some sun4 models)
#options 	KGDB			# support for kernel gdb
#options 	KGDB_DEV=0xc01		# kgdb device number (this is `ttyb')
#options 	KGDB_DEVRATE=38400	# baud rate


## Compile the kernel with debugging symbols (`netbsd.gdb' is the debug file),
## such that gdb(1) can be used on a kernel coredump.

#makeoptions	DEBUG="-g"


## Adds code to the kernel that does internal consistency checks, and will
## cause the kernel to panic if corruption of internal data structures
## is detected.
#options 	DIAGNOSTIC	# extra kernel sanity checking

## Enable (possibly expensive) debugging code that may also display messages
## on the system console
#options 	DEBUG

## Make SCSI error messages more verbose when explaining their meanings.
options 	SCSIVERBOSE

#options 	MIIVERBOSE	# verbose PHY autoconfig messages

## `INSECURE' turns off the kernel security level (securelevel = 0 always).
## This allows writing to /dev/mem, loading kernel modules while multi-user,
## and other insecurities good only for development work.  Do not use this
## option on a production machine.
#options 	INSECURE

## `FDSCRIPTS' allows non-readable but executable scripts by providing a
## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
## opaque file mechanism.  Perl calls this "secure setuid scripts."

#options 	FDSCRIPTS
#options 	SETUIDSCRIPTS

## Options for compatibility with previous releases foreign system binaries.
## In the cases of COMPAT_SUNOS and COMPAT_SVR4, you may need to set up
## additional user-level utilities or system configuration files. See
## compat_sunos(8) and compat_svr4(8).

options 	COMPAT_43	# 4.3BSD system interfaces
options 	COMPAT_10	# NetBSD 1.0 binary compatibility

## NCR5380-based "Sun SCSI 3" VME SCSI controller.
## This driver has several flags which may be enabled by OR'ing
## the values and using the "flags" directive.
## Valid flags are:
##
##	0x01		Use DMA (may be polled)
##	0x02		Use DMA completion interrupts
##	0x04		Allow disconnect/reselect
##
## E.g. the following would enable DMA, interrupts, and reselect:
## si0	at vme0 addr 0x200000 irq 3 vect 0x40 flags 0x07
##
## By default, DMA is enabled in the driver.
