436 set, then it is the second unit (according to info from Hauppauge).
437
438 However, while this works for most cards, I have seen a few PVR500 cards
439 where both units have the same subsystem ID.
440
441 So instead I look at the reported 'PCI slot' (which is the slot on the PVR500
442 PCI bridge) and if it is 8, then it is assumed to be the first unit, otherwise
443 it is the second unit. It is possible that it is a different slot when ivtv is
444 used in Xen, in that case I ignore this card here. The worst that can happen
445 is that the card presents itself with a non-working radio device.
446
447 This detection is needed since the eeprom reports incorrectly that a radio is
448 present on the second unit. */
