It appears that both the SLC and the 4/110 get as far as mounting
root (after mounting it to copy /netbsd), but hang badly there; this
may have to do with some problem with NFS read and write sizes.
The 4/110 crashes horribly upon encountering bwtwo0; it only makes
it far enough to get "RPC timeout for server 0xc0815411" when the
card is removed.  (bwtwo0 is a P4 mono framebuffer from a 3/80.)

This is with a 1.2 BETA kernel.  I'll be poking around at the other
aspects of this later.
