Aha, see why this is happening and have a patch almost cooked up.

Password from the shell is trying to check that the password you entered matches
the crypted password you gave after "password --md5" which was null --> go boom.
If you want to get an md5crypted version of a password try using md5crypt
instead, but I will fix this so it doesn't segfault :)

at http://people.redhat.com/~katzj/RPMS/ if you'd like to test.

Applying the latest grub from ~katzj and then figuring out how to get grub to 
install itself into /boot permitted me to re-enable the floppy in the ISP 1100 
BIOS and still have the system boot.

Bizarre, but worth documenting for the next victim who comes along.
