I'll have to check into 4 & 5, there might be a good reason for it. For
instance on a four port HP ethernet card (pci-pci bridge + 4 tulips) all
4 of the rom resources are mapped to the same address, which afaict, is
allowed but breaks things in mysterious and subtle ways.
That said, the parisc pci code is a rats nest...
