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).

    Is this really the same problem you experienced? I ask because you seem to have posted this as an answer to multiple questions, and the problem here is not that the touchpad isn't recognized, but that the driver for another device is also loaded, and that driver is the one that is active. You might want to edit this answer to make it more specific to this question. – Eliah Kagan Sep 16 '12 at 15:48

    I must admit I've copy-pasted this answer to several threads regarding Alps touchpad. On some of them this isn't the real answer to the question that was asked, but this is really exactly the same problem I had. – JKMirko Sep 22 '12 at 00:20

Referring to my own post, this is the solution that I found after reading many forums. I use a Dell Inspiron 14R, and now the touchpad is detected & gestures are working. Save the following in a .sh file, make it executable, and just run.

#!/bin/sh
cd /usr/src/
sudo wget http://www.dahetral.com/public-download/psmouse-alps-dst-1.2.tbz
sudo tar jxvf ./psmouse-alps-dst-1.2.tbz -C /
cd /usr/src/psmouse-alps-dst-1.2
sudo dkms add .
sudo dkms build -m psmouse -v alps-dst-1.2
sudo dkms install -m psmouse -v alps-dst-1.2
sudo modprobe psmouse
echo -n "Installation complete"
