Comment 1 for bug 235463

Yes, I tried dropping the madwifi tweak in the hardy cycle. As you found, what came out of it was bug 202453.

wpasupplicant working alone + network manager not working is almost certainly a driver bug..

Unfortunately, I can't debug that driver without having a card that exposes that behaviour; only thing i can do is dropping that tweak again - which will surely happen when NM 0.7 gets uploaded.
