Some (All? Sorry, covering arse here) cards (e.g. Saphire radeon 9600
- - whch uses an rv350 chip) have two PCI id's covering the same
physcial card. I originally asked about this back when the r300
project started. Apparently Windows requires the two pci id's in order
to see the two CRT controllers that the cards have.

X ignores it & accesses everything via the first pci id. (In fact IIRC
X doesn't even work through the second head pci id at all, so don't
even try to use it).
