Binary package hint: ubuntu-express

I'm on an Acer Aspire One 721-3574.

The symptom was that I couldn't enable wireless with any of the usual
tricks. After doing a bit of research and playing for a few hours/days,
I finally figured out that for whatever reason, the acer_wmi kernel
module was soft blocking every wireless card on the laptop (external usb
nic's too).

I demonstrate this here:
http://paste.pound-python.org/show/6078/

Immediately after line 63, the hardware wireless indicator lights up for
a brief moment, and is then re-extinguished.

acer_wmi doesn't seem to have much utility, is obviously buggy, and
should be blacklisted--possibly as an update and definitely in the 11.10
if the problem hasn't been fixed by then.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Fix Released
