Yes, swapping over NFS is error prone regardless. NBD is really the best way
to go (the patches for swapping over NFS are quite out of date), but swappi=
ng
to a loopback-bound swapfile over NFS still works in a pinch.

You're better off just using mtdram or something and swapping to unmapped
VRAM.
