Thanks.  I've done some tests.  Written up at #11170.

I've seen that as well, only on the XO-1.75 B1.  It reproduces in
OpenFirmware with "test /mouse".  Yes, the jumps are especially likely
on a button down.  The jumps are between one third and one sixth of the
screen dimensions, and always in either X or Y coordinate.  Written up
at #11171.

Yes, I think so.
