well, it should be possible, I found a small comment about this:

"Special Atheros Linux Driver for all Chipsets  available with extended 
Frequency range from 2.3ghz to 6ghz and costumized channelset and channel 
bandwidth available on request as binary or source code- royalties apply - 
please inquire."
(on http://www.minipci.biz/support.html - at the end of the atheros entry)

AFAIK ubnt.com sells drivers for these uncommon frequencies too...
But I don't know how much it costs, but I guess it's "much more" than $5000!
