problem with touchpad on acer aspire 5750g

[Dmitry Batiyevskiy]

Hello
I have a problem with touchpad on my acer aspire 5750g.
It is recognized as PS/2 mouse, and scrolling on the touchpad doesn't works.
The first thing I tried was to update to 11.10 from 11.04. It wasn't 
helpful.
Then I tried to compile my own kernel with patch as advised here 
http://pj.freefaculty.org/blog/alps-touchpad-linux-final-statement-now 
(patch is https://patchwork.kernel.org/patch/350841/), but it don't fix 
the problem at all.
I tried to patch 2.6.38.8 and 3.0.4 kernels, sources downloaded from 
kernel.org.
If any body can help me I will appreciate.
"xinput list" shows:
⎡ Virtual core pointer                          id=2    [master pointer 
  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer
