That can't be true. There is at least StarOS product which can work as 
an AP and can support every channel. Even the ones which is not in any 
regulatory domain (I think?!)

Actually as a matter of fact I have few Senao APs which has Atheros 
minipci cards inside and they also allow regulatory domain setting so 
that some channels become activated and some are disabled etc. depending 
on the domain you choose.

New: Special country code '##' can be used to unlock all channels 
supported by the Atheros hardware (2312-2732, 4920-6100). It is up to 
the end user to ensure they stay within their region's regulatory 
channel ranges.
