425 set, then it is the second unit (according to info from Hauppauge).
426
427 However, while this works for most cards, I have seen a few PVR500 cards
428 where both units have the same subsystem ID.
429
430 So instead I look at the reported 'PCI slot' (which is the slot on the PVR500
431 PCI bridge) and if it is 8, then it is assumed to be the first unit, otherwise
432 it is the second unit. It is possible that it is a different slot when ivtv is
433 used in Xen, in that case I ignore this card here. The worst that can happen
434 is that the card presents itself with a non-working radio device.
435
436 This detection is needed since the eeprom reports incorrectly that a radio is
437 present on the second unit. */
