Personally I've never had any problems with the tulip driver starting
with version 0.90 and a Linksys LNE100TX rev2.0.

Actually, TCP uses ICMP respones for things such as "Destination
unreachable". If you can't get ICMP packets in then you will never
get any TCP error messages, just timeouts.
Do you have the installation stuff on the NFS export? It may be
easier to download rescue and root floppies from the potato installers
and do a network install. You'd be using a 2.2 kernel then.
HTH,
