With MacBookAir 4,1 touchpad stops working abruptly

[Clint Byrum]

After logging in, within 1 minute, the trackpad just stops working. I had to install xserver-xorg-input-mtrack, which is not nearly as good as the regular evdev/multitouch driver for the trackpad.

I'll attach Xorg.0.log.old to the report, hopefully that will help debug the problem.
