A quick suggestion that might not be practical: have you tried using the
linuxinput driver instead?
For example, when I compiled Qt for the Kobo Mini, I compiled it with
linuxinput support (-qt-mouse-linuxinput) and selected the driver using an
environment variable at run-time:
I've always had difficulty with tslib but linuxinput has mostly worked for
me, once I've figured out which device file it needs to read from.
