I'm worried that this would make it less reliable and predictable. If the value
is really really low that may be interesting to avoid disabling the touchpad
caused by accidental bumps of the trackpoint. But the flipside of this is that
it would require more movement to disable it when intentionally using the
trackpoint, so a user resting the palm on the touchpad may see fake touches if
they haven't moved sufficiently.
besides, this wouldn't help much with your current issue, because you use the
trackpoint "vigorously", which surely is above any threshold, right? :)

A palm touch can in some cases look like two-finger scrolling. Though with
newer touchpads that shouldn't be much of a problem so this may be an
interesting approach. I don't have time to work on this right now though, but
feel free to have a go at it.
I guess a simpler solution would be to reduce the timeout, but 300ms seems
quite short already.

Just to confirm, you're still getting events out of the trackpoint when this
recalibration happens, right?</pre>
