Can you try the patch from PR port-i386/39299 instead?
Yes, and it seems to fix the problem.
What I've ran was gqmpeg (=mpg123 frontend) and firefox. The former for some
FPU intensive application, the latter for GUI. Kernels that I've tried are
4.99.72 from Oct 1st without your patch, and 4.99.73 from Oct 16th with your
patch, both on a Toshiba Portege 3440ct with NetBSD's new native X.org and
the "savage" driver.
The test case that I've tried while playing music in gqmpeg was to move the
mouse cursor across Firefox menues (built-in ones plus items on the toolbar),
and with the unpatched kernel the mouse cursor often skipped to the left site
of the screen, often into the upper left corner. Booting the new kernel, this
jumping does not seem to occur.
Not knowing any further implications of your patch, I'd give it a thumbs up.
