Yes!  I just discovered that I can multiboot the netbsd kernel off
of a FAT32 fs or even an NTFS fs, but *not* off of a UFS fs :o/

Apparently "something bad" happens to the kernel in the process of
reading or loading it from the UFS fs.  I can read small text files
from a UFS fs, however, so I'm thinking maybe this has something to
do with the size of the netbsd kernel?

BTW, I've tried booting the netbsd kernel off of a FreeBSD UFS1 fs
but I can't tell if my NetBSD partition is UFS1 or UFS2 -- dumpfs
doesn't say which kind it is.  I confess I really don't remember if
I have any UFS2 partitions or not.

Excellent work so far in just one day!  Got any other tricks? :o)
