Is there anyone out there who has successfully booted a sparc via NFS?

My sparc panics when it tries to mount the swap file, claiming a corrupt 
RPC struct.  I wonder if my swap file is not properly set up.  Can 
somebody tell me what they did to get a working swapfile?  Can you show 
me your /etc/bootparams, and a ls -l of the files mentioned therein?
