f you wave the mouse pointer furiously, the lag gets up to at least 0.5s
when mouse pointer slows down to a crawl when the playback gets to the
end of the buffer of recorded stylus events. Neither the trajectory or
the velocity of the stylus faithfully reproduced.

Also, you wiggle the stylus around and then lift the stylus and a few
seconds later, put it down somewhere else, the input that was recorded
before the stylus was lifted will be played (in the original location)
once the stylus is put down again.

The input smoothing is especially atrocious.  Tracing out a square on
the tablet causes the mouse point to trace out a wildly distorted pin
cushion. Tracing out a square but pausing for 0.3s at the corners causes
the mouse pointer to trace a proper square slowly but with no pauses. It
acts like a really poor attempt at input conditioning has got into the
works.

Attached is the xorg.conf file I'm using at the moment. (It does not
help the awful 0.3s stylus motion lag with my ArtZ II tablet.)

My system is running Ubuntu 9.04 with the 2.6.28-14-generic kernel.
