I had exact same problem on my Inspiron N5110 running Ubuntu 12.04 but was able to fix it using patch and instructions provided in these two links.

Touchpad is now recognised as a AlpsPS/2 ALPS DualPoint TouchPad and Touchpad tab is enabled in System Settings. Unfortunately, scrolling is still not an option... :-(

At least touchpad is disabled while typing, which was the biggest problem for me resulting in cryptic writings! :-)

[EDIT]: Also Fn+F3 is working now (aka, touchpad toggle).
