Well, while we are at it, we could also work on fixing the PCI problems:
Instead of relying on XFree knowing the host bridge and deducing the
iobase, I beleive we should export from the kernel either one iobase per
PCI device (there can be different busses with different iobases, that's
the case on the new macs and they have the same bus number), or we can
have /proc/bus/pci export "fixed'up" IO addresses (already including the
iobase).

I can code those fixes, but I'm not sure what solution has most chances
of beeing accepted (especially changing /poc/bus/pci semantics). The
problem is that exporting an IO address alone (without the iobase) has
really no meaning on arch that don't have a x86-like separate IO space at
the CPU level.

Have you talked to Martin Mares about this?
