The same thing on IBM ThinkPad R31 when using TrackPoint. The issue: on any continious mouse move, or rapidly repeated mouse button press mouse jumps to rnadom screen edge, and makes random clicks.
Dmesg report on error: [ 3014.824000] psmouse.c: TrackPoint at isa0060/serio4/input0 lost synchronization, throwing 2 bytes away. [ 3022.808000] psmouse.c: TrackPoint at isa0060/serio4/input0 lost synchronization, throwing 2 bytes away. [ 3158.128000] psmouse.c: TrackPoint at isa0060/serio4/input0 lost synchronization, throwing 2 bytes away. One line each time the mouse goes crzay. Notice: The mouse works fine till the desktop gets loaded i.e. it never jumps at logon screen, but does so on Gnome, XFCE, and fvwm-crystal window managers. USB mouse (A4Tech WOP-35PU) works fine. Add-on: Here are some dmesg complaints that may somehow affect mouse (or not). [ 13.927370] Local APIC disabled by BIOS -- you can enable it with "lapic" ...
