Description:

The touchpad on these laptops is only recognised as a standard PS/2 mouse by X11. Using the patch supplied at [0] with the stock kernel from ABS makes it properly detected (applying it last, if it makes any difference). The stick is also getting recognised at the same time.

Still present with
* linux 3.1-4
* xorg-server 1.11.2-1
* xf86-input-evdev 2.6.0-4
* xf86-input-synaptics 1.5.0-1

Patching the current ABS Linux package (linux 3.1-4) with the attached patch (less than 10 lines including sources and md5sums) fixes this problem.
