hmm my fault i forgot to swap values for big endian machines...

It's a 5413 i must fix that function that matches ids with names soon :P

FYI later 5424/2424 have a 4K EEPROM (v 5.3) that is not supported
yet, also your regulatory domain is ETSI1_WORLD

32KHz crystal is used for power saving

Nope it's fine, it might be that 5006X's RF part is not initialized
propertly so it doesn't "hear" 5004X.

Typicaly you should connect the antenna on main (actually on my CM9
-lol we also have the same 5004X card- i connected both antennas so i
haven't checked that).

yup but it's not implemented yet in ath5k (hw functions for this are
ok we just don't use them yet as far as i know -i'll check it out to
be sure).
