Ok, good point. :) And I guess we should assume that anyone who is
still having the problem has not had success with any of the
workarounds. I guess ideally, out-of-the-box, either with GENERIC or
GENERIC with SCHED_ULE, they should not see jerkiness, and if they do
they should report it here.

Ahh, I'm running SMP here, so that could certainly be part of the
reason just using sysmouse worked for me. Although I personally would
like to know why it's jerky when using psm0, and perhaps it might help
someone with a UP setup? If so, would the schedgraph info be useful?
If not, I'll butt out and let someone who's still having the problem
chime in. :)
