The problem is, there are PCI device drivers which assume you can get
an address in I/O space from a PCI device (either directly from the
config-space base address registers or from the pci_dev struct) and
then just do inb and outb on that port address. That's why inb/outb
add _IO_BASE to the port number.
One way might be to adjust the base addresses in all the pci_dev
structs and then make sure all drivers use the address from the
pci_dev struct rather than reading config space themselves.
Paul.
