Fix touchpad scrolling on Acer 3820tg with patched driver

After reinstalling Natty (botched attempt at moving to Oneiric Unity/Gnome3) I was reconfiguring my system. while looking up the imps mouse fix I found a post on the Ubuntu forums which referred to a synaptic bug with a patched driver.

With the patched driver the touchpad indicator finally works on my TimelineX 3820tg! Yippeee!

Here's the bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550625

Here's the link to the driver: http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.9/psmouse-alps-dkms_0.9_all.deb

An updated driver can be found here: http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.10/psmouse-alps-dkms_0.10_all.deb
This version appears to be the one that will be added to the 3.3 Linux Kernel.
