Great.

Note that in mainline there are now two versions of the driver for
at76c50x usb wireless cards: net/wireless/at76c50x-usb and
staging/at76_usb. My testing shows that there are still problems with
the former, while the latter staging driver (the older of the two) is
okay.

Therefore I would recommend sticking with the staging version (as used
in Jaunty) for the time being.
