For one thing, why shouldnt FreeBSD able to do that?
The other thing is that I thought atheros doesnt have firmware and the 
driver handles the regulatory domain settings. Thats why atheros is not 
giving out the source code for their drivers (I think there was such 
problem)

Anyhow. I am not a pro in this so I better shut up :) But it is possible 
to enable all the channels etc. available in atheros chip from the 
driver. At least StarOS is able to do it so...
