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