Yes, I was seeing this. ARP on the NFS server showed the
client's ethernet address, so something was getting through to the
server. ARP on the client (using the floppy root filesystem) showed
the NFS server, but it didn't have its ethernet address as I would
have expected - it was showing both the server and client with all 0's
in the ethernet address field.

I could play with this some more if you need me to, but I
worked around the problem by putting an IDE disk on that machine.
Actually, generating the 'init==ksh' root floppy wasn't really all
that hard either, come to think of it.
