Problem with Vaio touchpad



-----BEGIN PGP SIGNED MESSAGE-----

Hi. Up-To-Date Sid on a Vaio PCG-GRT170.

I finally tracked down the problem I've had trying to go from kernel 
2.6.10 to 2.6.11, which I noticed recently became the "official" 
latest Debian kernel. Or rather, 2.6.10 is showing up as obsolete 
today.

Anyway, when the "psmouse" module loads in 2.6.10, I get the following 
message:
- -----------
~# modprobe psmouse
input: PS/2 Generic Mouse on isa0060/serio1
- -----------

and everything works just fine. Smooth fine position control, 3-button 
emulation, copy/paste, strike the touchpad surface and it "clicks" 
button 1, stuff like that.

However, under 2.6.11, the following message comes up:
- -----------
~# modprobe psmouse
ALPS Touchpad (Glidepoint) detected
  Disabling hardware tapping
input: AlpsPS/2 ALPS TouchPad on isa0060/serio1
- -----------

Fine movement is no longer smooth, distance is inconsistent, 
copy/paste is flaky to say the least, and worst of all there is no 
"click" when I hit the touchpad with my finger.

Is there a way to disable checking, to force "PS/2 Generic"-ness upon 
the module? Sometimes hardware detection can go too far, it seems.

I'm not going to open a trouble ticket on the module until it's 
obvious there is no way around the detection routine, or I can 
communicate the action and fix to the kernel packagers.

Curt-
