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

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