The NFS file handle is a variable-length byte array (32-64) for nfs v3.
Ultrix emulation does v2, so you need to pass the native NetBSD mount
call the v2 filehandle you got from the Ultrix syscall, and set the
length (fhsize) to  NFSX_V2FH. The latter is defined in nfs/nfsproto.h.

The emulations slipped my mind.. Sorry about that.
