Hi,

I had a similar problem with recent kernel 2.6.x and gpm.
Solution : the psmouse module is missing
  modprobe psmouse
and the mouse is immediately available, no restart of gpm necessary !
lsmod shows that noone (count == 0) is using the module !
Removing the module and the mouse is away.

Hope this my help you,
Lothar
