Ever wondered why the signal was so bad with p54 compared to madwifi, or intel?
Well, if you have revision 1 rssi calibration curve points in your EEPROM, then wonder no more.
The firmware wants a extra 1 byte padding for every curve point. But someone forgot to put
them into the EEPROM's data structure...
So now, big question: what happens when we blindly "memcpy" these data points?

Only rev 1 and 2 ssb SPROMs have fields named et0mac and et1mac;
however, all of the extraction routines extract pseudo data for these
fields from regions that are all 1's resulting in a hardware address
