It should be possible. I can suggest two ways. If you want to make
it look really like a diskless boot, you can probably hack the code
in /usr/src/sys/nfs/bootp_subr.c to pretend it sends a request and
pretend it receives a response and hard code the IP address and
root path in there.
Alternatively, and slightly less hacky, you could build a kernel
with an MFS root and include enough commands to mount the nfs root
on /nfsroot and symlink everything else into place.

The second method mentioned above should work for this machine too.
