Managing a standard userland image

It should be possible to avoid the chroot and just mounting NFS-root.
If the network card is on pcmcia, pivot_root works fine after running
cardmgr. I can get back what I've done with the Assabet a while ago
if there's interest.

Kernels are not compatible, but userland is. I'm using the same filesystem
with both devices. [Well, there might be PXA stuff that doesn't work with
SA, but not in standard setups]
