Late to the party, pardon...

FWIW, there _is_ a problem w/ mac80211's pre-authentication scanning.
It doesn't probe for SSID, so it can't see hidden networks.

I have been testing the patch below with some success using the
wireless-tools package.  However, NM still seems unable to get an
association, at least not on the first try.  Sometimes/often the 2nd
or 3rd try works, whereas w/o the patch it basically never succeeds
without some sort of command-line intervention.

Anyway, perhaps you can test w/ the kernel patch below applied?
It is also available in the Fedora rawhide kernels here:

Thoughts?
