FWIW, the drivers generally use default values from EEPROM. Ideally, drivers would automatically adjust to Tx power in accordance to the current regulatory domain. But at present there is no support for regulatory domains, either. You could hack the driver you're using to write a different tx power threshold to hardware. If you manage to do that, please consider helping us with adding support for regulatory domains, which would then be configurable from userspace.
