So if you can reproduce the issue without NetworkManager in the mix,
that helps narrow down the problem.  This definitely seems like a driver
problem to me.  If you provide the wpa_supplicant config files to the
madwifi driver people, likely they will be able to help you debug why
their WEXT support isn't working here.

The atheros situation will hopefully get a lot better in a few kernel
versions because the ar5k mac80211-based driver will be upstream.  And
it'll have the same WEXT problems that iwlwifi and bcm43xx and all the
others do.  Which means it'll likely work quite a lot better than
madwifi.
