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