I now increased the pressure threshold. Just for the archives, I am
using the following settings:
Option "FingerHigh" "55"
Option "FingerLow" "50"
This is high enough to stabilize the mouse position on the end of mouse
movements significantly. The downside is that I am missing an
occassional click here when I tap to lightly.

Thanks, that's great. If this patch is added, will we still need to
manually set a dead area on the buttons? Or is there a possibility to
change the default config files so that if there are clickpad buttons,
those are automatically marked as "dead area"?
