I am able to use the touchpad in Dell Inspiron N5110 now. Thank you very much.

Steps I followed:

Download http://www.dahetral.com/public-download/psmouse-alps-dst-1.0.tbz/at_download/file

Install Dynamic Kernel Module Support package if you don't have it already:
$ sudo apt-get install dkms

Extract the downloaded package and move it to the /usr/src location:
$ cd download_path
$ tar xf psmouse-alps-dst-1.0.tbz
$ sudo mv usr/src/psmouse-alps-dst-1.0 /usr/src/

Build and use the module:
$ cd /usr/src
$ sudo dkms remove psmouse/alps-dst-1.0 --all
$ sudo dkms build psmouse/alps-dst-1.0
$ sudo dkms install psmouse/alps-dst-1.0
$ sudo rmmod psmouse && sudo modprobe -v psmouse

Now go to System Settings -> Mouse and Touchpad. You should see the Touchpad tab also :-)
