2.6.24.3-12.fc8 kernel causes NM to fail to connect, 2.6.23.15-137.fc8 works perfectly

  [ 1 ] Bug #433262 - RTC disabled in recent 2.6.24 builds for fc8 && rawhide
        https://bugzilla.redhat.com/show_bug.cgi?id=433262
--------------------------------------------------------------------------------

If I do /sbin/iwlist wlan0 scanning I can see both my APs showing the
correct frequencies, encryption capbilities, SSIDs and MAC addresses,
it's just that the connection never activates and the right hand green
dot on the icon never occurs, it falls back to repeatedly asking for
the WPA key even though gnome-keyring has it. Reverting to the
2.6.23.15-137 kernel makes it work instantly again.

If someone would like to tell me what sort of debugging I can do, I'll
happily do so and post the results here.

Fun this wireless lark eh?
