Why do you say "still"?

If there is a precursor to this bug, could you please link to it?

As for the trackpoint, we can't check this without the hardware. I know that
ThinkPads have sysfs settings for their trackpoints - maybe your Dell
trackpoint has them too and you can use them to turn down the sensitivity? If
yes, then we can come up with a udev rule for your stick.
