Problem Description:
On kernels of the 2.4.xx series, the mouse works fine, with mouse wheel and
everything. 

But on 2.6.xx kernels, as soon as I move the mouse, the light goes off. It only
goes on again if I unplug and replug the mouse in the PS/2 socket. 

Strangely, it detects the mouse as an ImExPS/2 mouse, but it is a simple ImPS/2
mouse. At first, I thought that the protocol was the problem, but limiting the
max_proto to ImPS/2, either by kernel variable or by editing the psmouse_base.c
and removing all the other protocols, proved me wrong. 

I'm sorry for not having much more information. If you need my cooperation, feel
free to e-mail me and ask for more info.

Steps to reproduce:
After booting, move the mouse and the light goes off.
