1 . The touchpad of my laptop doesn't work with the 2.6 Linux kernel, 
but works with the 2.5.70

2 . I allways test the new Linux kernel, and my touchpad worked. It 
works with the Linux kernel 2.5.70, but doesn't work thos the 2.5.75. I 
use in the XF86Config the device : /dev/psaux. When I start X, the mouse 
appaears, but I can't move it ! My laptop is a Samsung V20. I try to 
configure X with /dev/input mouse0 or /dev/input/mice, but it doesn't work.

3. mouse, Xfree, touchpad, /dev/psaux
