Basic questions:

 - Can you reproduce this with a 3.x kernel from sid or
   experimental[1]?  The only packages from outside squeeze you should
   need to install to test that would be linux-base and
   initramfs-tools.  If the problem is reproducible that way, we can
   get help from upstream, and if not, we can figure out when it was
   fixed and try to backport the relevant change to squeeze.

 - Please elaborate on "I had to modprobe psmouse to set it right".
   What steps should I perform to reproduce this bug?

 - Please send /var/log/Xorg.0.log and full dmesg output after booting
   and triggering the problem.

 - Any other weird symptoms?

Thanks and hope that helps,
Jonathan
