Last time I checked, ath5k did not support master mode, but the managed mode is 
very good (or better than madwifi-ng) and they fixed a lot of concept problems 
dealing with the creation/destruction of virtual interfaces (or so I was told).

BTW, you can set multiple APs (wlan0, wlan1, etc) with madwifi-ng, but 
everything is locked by the hardware interface (wifi0)... or by everything, I 
mean all your virtual stuff will have to operate under the same radio frequency 
(set on the hardware, in wifi0).
