Yes, but it is not yet fully implemented in the driver. 'iwconfig wlan0 txpower off' (and 'on') is supposed to do exactly this. prism2_ioctl_siwtxpow() in prism2.c has the places and TODO comments for turning the radio off/on.

Prism2 MAC has a test command for setting baseband processor parameters, including TX/RX power enable. I haven't tested these yet, but I would assume that this can be implemented without problems. One just needs to be quite careful when using the test command, since there is no error prevention mechanisms and there is a change of breaking something..
