Wakeup on mouse movement

[Matthias Grimm <matthiasgrimm@users.sourceforge.net>]

Hi,

I just upgraded to the debian kernel 2.6.18-3 (I used a self-configured
kernel before) and found an odd behaviour:

When the machines was suspended to RAM it woke up again after I
moved the mouse. In the past The machine woke only up after triggering
a key on the keyboard but never on mouse movement.

Is this a feature or a bug? How could I disable this "feature" in case
it is one?

I used the 2.6.18 kernel before with my own configuration and it never
woke up on mouse movement. 

 Best Regards
   Matthias
