That's false.
Atheros does not produce distinct chips for different countries or
markets.
<http://marc.info/?l=linux-wireless&m=125072768530674>
There is only ONE chip, with custom "regdomain" values in the EEPROM.
And the *driver* applies constraints based on that value. No more no less.
Then, crda/wireless-regdb only can narrows things a bit more.
Atheros chips can go beyond IEEE 802.11 frecuencies.
dd-wrt is selling "DD-WRT Superchannel Extension":
http://www.dd-wrt.com/shop/catalog/product_info.php?cPath=22&products_id=717
[...]
SuperChannel allows you to use special frequencies
from 2.3 Ghz - 2.7 Ghz (802.11g capable devices only)
and 4.9 Ghz - 6.1 Ghz (802.11a capable devices only).
[...]
Please note that the DD-WRT Superchannel license can only be
applied to certain routers equipped with Atheros based WLAN-hardware.

Mikrotik also sells a 'code' to unlock "custom" frequencies:

Ubiquiti used to do it: http://www.qsl.net/kb9mwr/projects/wireless/airos-ham.jpg
