Comment 40 for bug 714862

Well, not that I'd tell you are wrong, Eric, but the problem isn't in linux kernel itself.
To get AR3011 working by default I've just removed libmpt-runtime as in this bug report http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=641749
To be honest, actually I've got Acer TimelineX and acer_wmi got some complaints about device state, so I've rebooted into win7 and turned up my AR3011 -> reboot into Ubuntu, but with laptops without software switches like that shouldn't be the case.

Now it works flawlessly again, without any custom kernels or dkms.
