Are you sure you are allowed to transmit at that power level ?
ath5k/mac80211 use crda and the wireless regulatory db to determine the
maximum allowed transmission power. Start by verifying the allowed power
limits by the driver (you should see a list on dmesg or with iw) and
then if it's not related we can see if it's a driver bug. From my tests
CM9s work fine with ath5k.
