Oh boy:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/input/elantech.txt#n547
"3 finger touch only reports the position of the center of all three fingers."

And I think HW v2 is the same given that they also report a common packet when
there are 1 or 3 fingers on the touchpad.

Mildred, would you mind sending an other ps2emu record with:
one finger down, wait 1-2 sec, drop an other one, wait, drop a third one, wait
and release.

I want to check if the given coordinate is actually the "center of all
fingers".

Peter, I am not sure we will be able to fix something in the kernel for those
devices. How about we just disable palm detection for semi-mt devices?
