I downloaded madwifi with apt-get source madwifi and then used module assistant to build it, so I'm not clear what you mean by "which we do not have source for". I would switch to ath5k if it worked for me - perhaps you would be so kind as to share a web URL that details the procedure for such a switch if you have it, preferably from someone who has an Atheros wifi adapter.
