Note that it could be interference from internal devices as well. The
driver simply reports the values from the hardware unmodified, so unless
there's some problem with interpreting the data (which seems unlikely at
this stage, but not impossible) the jump indicates a sudden change in
the position being reported by the touchpad. If you can enable the
packet dump and collect the dmesg data (*immediately* after you see the
jump, switch to a VT and collect the data without touching the touchpad
or trackstick) I'll take a look and see if I can identify what's
happening.
