We only really need it for /dev/pci*, because that lets you mmap()
arbitrary PCI space - things like wsfb or sbus graphics work without it.

We could easily do away with it by going back to using ttyE*, ttyF*
etc. - that would only allow using graphics hardware with kernel drivers
though. I did that back in the xf86 days, that way every graphics
device shows up as its own PCI domain, device 0:0:0, complete with its
own IO space, which can be quite confusing since it doesn't correspond
to the actual bus layout at all.

have fun
