I'm still puzzled how to handle the two different values that the EEPROM has, namely one for the bg band and one for the a band. I've handled it by registering the one associated with the configured band, but that seems to be unlikely to be correct.

So it would be fine with me by letting the user handle it completely. I see -- well if there are *some* cards that do have valid EEPROM values then it seems worth it to do the actual regulatory_hint(), for dual band cards you can probably just not support it. But its up to you guys. Just my advice based on the documentation I have read so far.
