412 However, while this works for most cards, I have seen a few PVR500 cards
413 where both units have the same subsystem ID.
415 So instead I look at the reported 'PCI slot' (which is the slot on the PVR500
416 PCI bridge) and if it is 8, then it is assumed to be the first unit, otherwise
417 it is the second unit. It is possible that it is a different slot when ivtv is
418 used in Xen, in that case I ignore this card here. The worst that can happen
419 is that the card presents itself with a non-working radio device.
