Right. But the point was that once you know how the motherboard does it,
it will continue to number that way. You can change the BIOS, change the
CPU, etc. and the pci bus will still number the same way.

So you can wire certain controllers down to certian PCI slots and be
certain they won't wander around (given the slot-to-dev mapping). 

Take care,
