psmouse synchronization loss under load

I have the same problem in 2.6.1: Infrequently the mouse(rather: the trackpoint) jumps around and clicks wildly on the desktop.... Extremely annoying. The log message is identical. I do not think it is dependent on load. It only happens when I USE the pointer though...

I am using Debian/unstable, X-4.3, linux-2.6.1 with alsa and the DSDT-initrd patch on my IBM Thinkpad R31 Mobile Celeron 1,2 GHz.
