I applied your v4 patch, and that fixes it somewhat insomuch as it it working, but it keeps resetting itself if i stop using it for a few milliseconds, so the mouse appears sluggish as it performs a reset whenever i use it. Here are the messages i see (100's of them).

Hi Dmitry,

Your patch (applied to 2.6.11.8) hangs my touchpad mouse totally.
The error i get on bootup

May  8 17:16:58 localhost kernel: alps.c: Failed to enable absolute mode
May 8 17:16:58 localhost kernel: input: PS/2 ALPS TouchPad on isa0060/serio1

without your patch

and the mouse works fine (except when it goes crazy and jumps all over the place). I've been suffering with the problem for a long while on this hardware..


Ahem, yep, I broke ALPS... Please try applying the patchlet below on top
of what I have posted or grab an updated version of the patch:
