I posted some comments here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1248287
Apple Trackpad indeed crashes kernel 3.12.0-031200-generic on SAUCY (and TRUSTY with 3.12). But 3.11.0-12/3.11.0-14 seem to be good.
I have tried TRUSTY alpha1, either 3.12.0-6/3.12.0-7, both of them crashes with trackpad.
AND, I also test Apple MagicMouse, none of mentioned kernel crashes with either SAUCY nor TRUSTY.......
