setup-pci is for SFF8038i devices. It therefore knows that for  
assigned
resources they must be I/O. It also assumes that zero is not a  
valid I/O
port just like zero is not a valid IRQ. Stick a real IDE resource  
at zero
and drivers/ide can't cope.

But 0 _is_ a valid PCI I/O address.  Do we now have to start
using "virtual I/O addresses", analogue to the IRQ situation,
or can these bad assumptions be fixed instead?
