I don't remember whether I've tested this with madwifi. If the driver
does not include all IEs (or well, at least WPS IE) in scan results, you
won't be able to use WPS. However, I would expect that you could use the
ath5k driver with your WLAN card.

I'm mostly testing with Atheros 802.11n card and ath9k driver and that
combination works fine. Anyway, this should work with any driver that
uses mac80211.
