471 
472            So instead I look at the reported 'PCI slot' (which is the slot on the PVR500
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

476            is that the card presents itself with a non-working radio device.
477 
478            This detection is needed since the eeprom reports incorrectly that a radio is
479            present on the second unit. */
