Public bug reported:
NetworkManager always reports "Wireless is disabled", and the acer_wmi
rfkill device in sysfs always reports state=0. Trying to write 1 to the
rfkill device state doesn't produce errors, but it doesn't produce any
results either, i.e. the state stays set at 0 and the wireless radio
stays off. Removing the acer_wmi module removes the rfkill device,
turning on the wireless radio.
I also tested this with upstream kernel using the
2.6.34-020634rc7-generic package from the Kernel Team PPA, with the same
results.
