411

413 PCI bridge) and if it is 8, then it is assumed to be the first unit, otherwise
414 it is the second unit. It is possible that it is a different slot when ivtv is
415 used in Xen, in that case I ignore this card here. The worst that can happen
416 is that the card presents itself with a non-working radio device.
