Sorry, I didn't explain myself very well. By "using a separate physical 
machine", I meant that I can successfully PXE boot the machine on my LAN 
which pulls the kernel over NFS and happily mounts root over NFS i.e. 
answer to your question is yes. The second part of my testing was using 
the mount_nfs command manually on the command line of a vbox vm which 
was booted into the fixit cd's fixit shell.

Everything points to my config being good and a weird loader related 
issue. Assuming you are able to successfully pxe boot FreeBSD could I 
ask you to please:

- Tell me which version of FreeBSD your pxeboot sources are built from

- Make your FreeBSD pxeboot binary available for me to download from 
somewhere so I can try it in case it makes any difference

Thanks for your continued input, I'm really at a loss.

Cheers,
Lawrence
