Peter and Adrian,
If this post is essentially asking to peek behind Atheros' kimono,
please disregard this post.
Is there any chance that the only diff between any two units is likely
to be the mac address and the regdomain?
IOW, do we know for certain whether the entire set of data required
for compliance in every country is stored on each and every chip?
No idea. I'm just saying I don't know for certain. I have EEPROM dumps, I've
just not sat down and investigated that.
As Luis has said however, the US (and Japan?) regdomain requires that card
domains aren't modified. I don't understand the exactness of the situation,
but as I've said, it's likely that merely ignoring/overriding the regdomain
is grounds for breaking the rules.
Adrian,
Me thinks a lot of our differences in point of view is that, IIRC, you
use the miniPCI cards in your development work and we have used the
integrated units since 2006.
Further, one who immediately loads 3rd party firmware onto an
integrated unit may miss this:

Country Code: Different countries will have different power levels and
possible frequency selections. To ensure device operation follows
regulatory compliance rules, please make sure to select your correct
country where the device will be used. The channel list, output power
limits, IEEE 802.11 and Channel Spectrum Width modes will be tuned
according to the regulations of the selected country. Additionally,
please consult the compliance guide for further explanation of
international compliance requirements.

IMHO, said devices are mostly a reference design provided by Atheros.
Remember me trying to say here a couple a weeks ago something about
guilt by association. One can't take on the country code of the AP
one is associating with and be certain that one is in compliance.
kind regards/ldv
