Allen,
        What else is plugged into USB?  (I.E. the output of lsusb)  I've heard
rumors of certain other USB devices causing mouse problems in ubuntu
8.10.  Usually this is a symptom of the system trying to set the pointer
via another device like a gamepad or such.  I had a similar issue a few
years ago where a touchpad that was going bad interfered with my mouse.
You could try unplugging all other USB devices or input devices other
than the keyboard and mouse and see if the problem remains.

        Ubuntu has moved mouse config out of xorg and into the HAL stuff.  You
can use "xinput" to see what devices X is recognizing and how they are
configured.  Try "xinput list"  to find out what the id for your mouse
is.  Then run "xinput test [idnum]" to capture all events from the
device to the console for a while.  Ctrl+c will stop the capture.  if
you run this you can see whether the events causing the motion come from
the mouse itself. (I recommend moving the mouse to the upper left corner
where it should report its location as 0,0)  If no events show up then
the mouse isn't your cause.  Test each input device in turn until you
find the one that is sending the spurious events.  

I hope this helps.
                        -Mike
