Can you do:

echo 1> /sys/module/psmouse/parameters/tpdebug

And send me the data log for the time you start moving
around to a few seconds after you start seeing the 
bad behavior?

Easiest way to do this is edit /etc/rsyslog.d and update the
kern.* line to:

kern.*   /var/log/messages

Then restart rsyslogd. When done, just email me /var/log/messages.
