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