sorry, should've checked myself first. Jump happens on single-finger to
double-finger change, see

Needs an axis range fix too, still using the traditional made-up synaptics
ranges and 5132 is quite a bit out of that...

Anyway, I noticed this is a touchpad from 2007. We have some code in place to
ignore jumps on finger count changes and that should/may work with this
touchpad but tbh, I don't have any spare time to invest in hw that's 10 years
old.

Given that we notice the jump and discard it, the worst bit right now is the
error message, right? So I'll just do the jedi-wave, tell you this is not the
error message you're looking for and close this as WONTFIX. Sorry.
