OK, Without this patch, My laptop suffers from jumpy touchpad and sticky keys. It's mainly because the Linux ACPI implementation is trying to access the battery state through the laptop embedded controller. The problem is that this access causes lost interrupts which leads to the above problems.

The patch was only for 2.6.14 and was not updated to 2.6.16. It doesn't apply. I was stuck until I decided to port it. It's working fine since a couple of minutes ;-)

Here it is anyway. But be aware. I feel the touchpad is not in the usual state I used to. I'm not sure how.
