418 However, while this works for most cards, I have seen a few PVR500 cards
419 where both units have the same subsystem ID.

422 PCI bridge) and if it is 8, then it is assumed to be the first unit, otherwise
423 it is the second unit. It is possible that it is a different slot when ivtv is
424 used in Xen, in that case I ignore this card here. The worst that can happen
425 is that the card presents itself with a non-working radio device.
