Following rtos' suggestion, I created one new file: 
~/usr/src/sys/arch/evbarm/conf/NSLU2_INSTALL

#    $NetBSD: NSLU2_INSTALL
#    based on ADI_BRH_INSTALL,v 1.1 2003/04/08 20:49:01 thorpej Exp $
#
#    NSLU2_INSTALL -- NSLU2 kernel with installation-sized
#    ramdisk
#

include "arch/evbarm/conf/NSLU2"
include "arch/evbarm/conf/INSTALL"

and patched two others:

I also changed the NSLU2 configuration file to include the FFS_EI option 
and rebuilt the kernel, build, and release targets.  I loaded the file 
"netbsd-NSLU2_INSTALL.bin" onto the tftp server, and lo and behold:

RedBoot> load -r -b 0x200000 netbsd-NSLU2_INSTALL.bin

Welcome to sysinst, the NetBSD-4.99.49 system installation tool.  This
menu-driven tool is designed to help you install NetBSD to a hard disk, or
upgrade an existing NetBSD system, with a minimum of work.
In the following menus type the reference letter (a, b, c, ...) to 
select an
item, or type CTRL+N/CTRL+P to select the next/previous item.
The arrow keys and Page-up/Page-down may also work.
Activate the current selection from the menu by typing the enter key.

If you booted from a floppy, you may now remove the disk.

Thank you for using NetBSD!

The installation option got as far as trying to partition/label the 
thumb drive, but failed with the message:

    Status: Command failed
   Command: disklabel -w -r -f /tmp/disktab sd0 'NETBSD-NSLU2'
    Hit enter to continue
--------------------------------------------------------------------------------
disklabel: partition b: partition extends past end of unit

But, I've been having problems with disklabel even when booting from 
NFS, so I'm not sure that means anything.  It would appear that rtos' 
method does work.

The saga continues...

Thanks for the help, Don
