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 Michael
