On a related note, I would actually prefer to get rid of this PCI_IOBASE default and move it into the architectures that really want it like this. The default when PCI_IOBASE is not set IMHO should be to also not provide inb/outb and ioport_map() helpers, but we need a little more infrastructure to actually make the kernel build in all valid configuration when we remove them.
