416 set, then it is the second unit (according to info from Hauppauge).
417
418 However, while this works for most cards, I have seen a few PVR500 cards
419 where both units have the same subsystem ID.
420
421 So instead I look at the reported 'PCI slot' (which is the slot on the PVR500
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.
426
427 This detection is needed since the eeprom reports incorrectly that a radio is
428 present on the second unit. */
