Touch pad not working correctly

I have an Acer Aspire 7735Z laptop.
I previously have OpenSUSE 11.4 installed and disabled the synapic tap functionality.

I have installed OpenSUSE 12.1 and am having endless frustrations with the touchpad.
When I boot up, I get an error message stating: “No touchpad found”

Problem 1:
Unable to turn off touchpad tapping

Problem 2:
Random clicking when I type fast, even if nothing touches the touchpad

Problem 3:
The right click doesn’t work correctly.

Besides disabling touchpad tapping in 11.4, there are no special settings/tweaks on my system.
This is a plain upgrade from OpenSUSE 11.4 to 12.1.
This is what the hardware info reports for the touchpad:
