I've taken mkp's initial work on superio.c and added some stuff, but in
the end am confused by where we actually get the interrupt number from
the card.  There's no such register in function 1 (where the interrupts
ultimately end up) and both registers on function 0 and 2 return 0,
which I don't think is right.  I'd thought that PDC would have set this
up.  There's not much I can do at this point until we can have some of
Grant's attention.

In the meantime, I'll try booting with all of this on the C3k.
