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