Everything but the radar detector is in freebsd-head. Oh, if it's talking about adaptive being "transmit rate" then yes, you can configure a static transmit rate (ifconfig wlanX ucastrate Y). Listen before talk is normal atheros CCA. it's done by the chip, programmed by the HAL and can be driver controlled if you know what code to add. By default it's set to the -62dBm level that you need for CCA.
