You need to set the regdomain/country code to match the channel set 
programmed in the eeprom.  The ath driver is missing some code to map 
the eeprom codes to the system-wide SKU+countrycode.  If you show the 
output of ifconfig you should see a regdomain code that comes from the 
eeprom.  For example, on my cards that have an FCC regdomain code I usee

ifconfig_wlan0="country US WPA DHCP"

I'll get to it eventually or you can take a look.  Note that changing 
the regulatory settings can only be done with all vaps marked down; 
otherwise you'll get an EBUSY argument.
