I am not sure what you are suggesting. I enabled this override only when ONUS is selected because I wanted it clear that users were taking their regulatory compliance into their own hands. I always want the module option at least visible so that you don't have to muck with modprobe.conf just to get ath9k.ko to load when it's compiled differently. For the second part, you want the ability to set the regdomain be a compile-time option like CONFIG_ATH9K_OVERRIDE_REGDOMAIN or something like that?
