NFSroot is broken for two reasons at the moment. The first is that I
rewrote much of the NFS code for better performance, and broke NFSroot
as I went. While it does compile again on 2.1.36, there's also a problem
with the networking code. As ANK updated the IP routing stuff, he seems
to have changed some things in the way you have to configure an interface
and route. As a result, the old interface handling in nfsroot breaks as
well (the problem is that the kernel ARPs for the NFS server, but drops
the ARP replies somewhere because it won't find a matching route).

Unfortunately, I don't understand ANKs new code too well. I've spent the
better part of two days on trying to figure out what I've been missing,
but haven't succeeded so far.
