I can confirm this behavior. It has nothing to do with NFS, just with getting
an IP address. Previous versions used to do lookup automatically as soon as
there was a support for DHCP or RARP compiled in. Now one should force it with
ip=both or ip=dhcp option.

I can't use mknbi-linux since I have a diskless Sparc X-Terminal. Now instead
of simply booting, I should say "boot ip=both". Rather annoying, to be honest.
Is there a way (like rdev or something) to teach kernel where to look for IPs?

Yes, it's safe (at least that's what I did and wasn't punished ;-).
Alternatively you can install the latest version of mount from woody.
