No, the bounds checks are important because some touchpads will report out of bounds
coordinates for some events which messes up the ballistics.

You should be able to set the max and min coordinates of you touchpad using sysctl, they
should override the probed ones and so provide correct operation.  If that is not happening
then this is a bug that needs to be fixed.

 Sorry, I updated to NetBSD 10 on my laptop and have not had X since, that has soaked a lot
of my hack time working on fixing that problem.
