It's been awhile since I've netbooted a NetBSD install (at least since
1.5.2 was fresh), and I know that netbooting can be a pain, but here
it goes.

Can you give us some details of your setup?  Are you positive that you
have all the correct daemons running? Can you grab a tcpdump of the
whole booting process?
Also what version of the prom are you running? The boot banner should
tell you. Also just in case, are you sure you have NFS running
correctly to serve up the kernel?
