Also the supplicant test used AP_SCAN=2 though, which could affect this.
The nm-supplicant-test is pretty old and probably shouldn't really be
used anymore.

But Vincent, can you get some supplicant debug logs when running NM, as
described here?

http://live.gnome.org/NetworkManager/Debugging

under the "Debugging WiFi Connections" section.  Specifically, we're
looking for /var/log/wpa_supplicant.log when you see failures using
NetworkManager.

Note though that this driver is not part of the upstream kernel, and its
quality is highly suspect.  Just because it works manually with
wpa_supplicant doesn't always mean the driver is OK.
