Right -- I did apply Paul's recommendations. The manpage isn't
necesarily going to know all the interactions between our TP, kernel
driver and xorg input driver. Experimentation and source review carry
more weight.

I assume Paul did both -- he's been looking at this for a while.

Now, in my experimentation with the values he supplied, it did not
make any difference.

Ok. Gentlemen, maybe it's a better idea to grab 2 XOs, setup 802 on
one, 802B1 on the other, and run a quick test with the stock settings,
and other settings you think might help.

Also, Paul, did you get any response from deployments on whether the
new kernel + xset values improved noticeably on the jumpyness?
