Warning: I assume no responsibility for anything that happens if you try this alpha software. It's not even a real alpha release of kismac. I can't seem to get this to work on my Mac Mini with Airport Extreme. It loads up and I can select the passive driver but when I start scanning, it can't load the driver. Then the airport extreme driver isn't loaded up again and the computer has to be restarted. If anybody's interested in experimenting: http://binaervarianz.de/downloads.php/redir.html?action=download&mirror=http&file_id=36 Edit: I got it to work by disabling automatic airport connection and disconnecting my ethernet cable when i restarted. Now it works like a charm.
