Yup, .class can not fully replace the address range lists, but it should
reduce the number of cases where the address lists are needed and thus
simplify maintaining them ;)

Analog TV cards usually have a have eeprom at 0xa0, with PCI Subsystem
ID and sometimes config info, serial number and such stuff ...
Everything else isn't critical, at least I'm not aware of any touble
cases in the analog TV world.
