I've not had success, but I've been bitten by the same problem.

I've run a packet-filter and watched nfs-mounts happen both from
Ultrix and from a diskless machine failing to mount root.

As far as I can tell, the only differences between ultrix packets
going to mountd & the ones generated by a diskless kernel is that
ultrix says its using auth flavour 1, and sends 88 bytes of info,
including things like the time, the machine name, the uid the mount
request is coming from, the groups that user is in, etc.
... the diskless kernel says its using auth flavor 0 & sends nothing.
The diskless kernel is sending requests from a privledged port
(1023). 

I got this far and gave up diskless booting a month or so ago..
