This is the config file I use on -current for my LX.

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

# Options for variants of the Sun SPARC architecure.
options         SUN4M           # sun4m - SS10, SS20, Classic, etc.

## 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'

# options       PCMCIADEBUG
# options       PCMCIACISDEBUG
# options       DIAGNOSTIC      # extra kernel sanity checking
# options       DEBUG


## 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

## 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

# compiler options
makeoptions     COPTS="-Os -pipe -mcpu=v8 -mtune=supersparc"

## 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_40

## File systems.  You probably need at least one of FFS or NFS.
file-system     FFS             # Berkeley Fast Filesystem
file-system     NFS             # Sun NFS-compatible filesystem client
file-system     KERNFS          # kernel data-structure filesystem
file-system     PROCFS          # /proc
file-system     PTYFS           # /dev/pts/N support

## File system options.
options         SOFTDEP         # FFS soft updates support.

## Network protocol support.  In most environments, INET is required.
options         INET            # IP (Internet Protocol) v4
options         GATEWAY         # packet forwarding ("router switch")
options         NTP             # Network Time Protocol in-kernel support
options         PFIL_HOOKS      # Add pfil(9) hooks, intended for custom LKMs.
options         IPFILTER_LOG    # Add ipmon(8) logging for ipfilter device

#### Disk controllers and disks

## The following flags may be set for the NCR53c94 based esp driver:
##      bits 0-7:  disable disconnect/reselect for the corresponding target
##      bits 8-15: disable synchronous negotiation for target [bit-8]

## sun4/300, sun4c, sun4m on-board SCSI, and FSBE/S SBus SCSI cards.
## Both `dma' and `esp' are needed in all cases.
## Two kinds of additional SBus SCSI interfaces are available.  One uses
## "esp at sbus" like the sun4c on-board; the other uses "esp at dma".
