I'd still recommend running a DEBUG kernel so when it asks you what to use 
for init you can specify /rescue/init which is statically linked.  You can 
also tell it to run /rescue/sh to see if you can get a shell to work.

Have you had any success with a miniroot kernel?  That should have a 
kernel and minmal filesystem in the same image.  If that doesn't work then 
you have a really interesting problem well beyond just configuring a NFS 
root filesystem.
