418 where both units have the same subsystem ID.
419
420 So instead I look at the reported 'PCI slot' (which is the slot on the PVR500
421 PCI bridge) and if it is 8, then it is assumed to be the first unit, otherwise
422 it is the second unit. It is possible that it is a different slot when ivtv is
423 used in Xen, in that case I ignore this card here. The worst that can happen
424 is that the card presents itself with a non-working radio device.
425
