Comment 5 for bug 903236

In order to see switch of kerner versions hold SHIFT during boot.

I had 3.0 kerner and my touchpad was discovered (xinput list) like ImPS/2 ALPS GlidePoint. Now I have installed 3.2 kernel:
ygerasimov@inspiron:~$ uname -a
Linux inspiron 3.2.0-030200rc4-generic #201112012035 SMP Fri Dec 2 01:36:30 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

and now touchpad is discovered as PS/2 Generic Mouse:

ygerasimov@inspiron:~$ xinput list

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=13 [slave pointer (2)]
