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
