Actually, It's just clicked in my mind that I *did* see NFS problems 
when first booting my big-endian VM to test in, but dismissed it as the 
old "NFS-over-UDP is flaky on the office network" issue and having 
forgotten to add the ",tcp" option as usual. Now I'm about 90% certain 
it will be my fault, and of where I slipped up. Expect a patch later 
this afternoon...

Thanks,
Robin.
