I do get some results on scans, but not as many as with madwifi.  Also,
it reports dramatically different signal strengths than madwifi (though
this may be because madwifi sets my maximun Tx power to 17dBm, and ath5k
sets it to 20).
I don't see any untoward CPU usage when ath5k is loaded.  wpa_supplicant
uses about 40% on one core, give or take.
