Patch attached; it boots to a login prompt but

a) keyboard is dead
b) serial port is dead

so ssh access only.  I included Joel's patch to gsc.c in the
attachment... no credit to me for that part.

Patch attached, which I think is the correct fix.  There are many
next_device() functions in the tree; we needed one that used
knode_parent, not knode_driver.

Still looks to me like drivers/parisc/sba_iommu.c needs this fix
too, but I've not actually tried it.
