Of course, strictly speaking we could separate between pci busses (where we
have configuration space accesses) and isa-like busses (where we don't).  I
don't see any advantage.  For port accesses, we don't have to separate.

Remember I still want to remove the IRQ handling out of struct pci_bus_ops.

The Dino-on-a-card I have in the A180C is quite long, yes.

Don't destroy any hardware ;)
