I'm seeing issues as well on my Dell Inspiron 8000 (yes, it has a Synaptics,
NOT ALPS as usual on Inspiron):

(without a mouse plugged in) after random times the pointer exhibits
clear signs of craziness, moving on its own (mild issue) or jumping
uncontrollably (worse) or being completely off-screen most of the time
(worst).

IIRC (I'm quite sure about this) the very first time that I've seen
this phenomenon happen on my notebook was around 2.6.9,
and I attributed this to broken/grown-old hardware on my notebook
(thus from then on mostly running with external mouse attached),
but since several people now report very similar issues
one would think that it's a driver calibration or touchpad setup issue
instead of actually broken touchpad hardware.

Plus, I'm sometimes having issues with pointer movement (cursor won't advance
any more unless I stop touching the touchpad for a few seconds to let it
reset somehow - probably a bytestream hickup issue).

Any clues?
