Since touchpad of my Dell Latitude E6420 was not workin properly in Linux, I started googling.
I found this Arch Linux AUR: https://aur.archlinux.org/packages.php?ID=51343
However, this just gave me basic functionality: no scroll, no multi-touch
Then, I patched vanilla kernel source with patches from http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.10/ and I used your scripts to compile and install the module; and now my touch-pad is fully functional (scroll and even multi-touch).
Here are files that I am currently using:
psmouse-elantech-build.AP.tar.bz2
psmouse-elantech-build.AP.patched-files-only.tar.bz2
P.S. I am running 3.2.2-1-ARCH x86_64
