Well, I don't, I just hope that it is so.

IIRC the wifi chip is the only device on PCI (but I could be wrong, I'll
double check when I can).

Most probably because the device has no internal eeprom. Apparently the
ar71xx platform had the same kind of problem, fixed by poking some
registers with the data from the flash, but I don't have any ar71xx
device to test, I just inferred that from the openwrt code (hence my
original question)

No, the board originally uses a propietary os with no documentation (and
much less sources) available (in fact they went out of their way to
obfuscate the original firmware in order to make it difficult to load
alternatives), however
1) from the log messages it seems it's using ath9k (i.e. the messages
are exactly the same as the ones I found in ath9k sources)
2) even the original firmware identifies it as ff1d, but then it sees it
as 0029 (just like after the pci fixup I copied from the ar71xx but with
the endianness problem I asked about).
Bye
