The answer is simple: there is no touchscreen calibration and
debounce/dejitter method in (unconfigured) Xorg for a long time.
At least I am not aware of.
I.e. we have to configure Xorg to load tslib and disable autodetection
An alternative would be to modify the touch screen
kernel driver to send calibrated (and debounced, dejittered)
events to the kernel. But the kernel can't read/write calibration
data and adding /sys nodes to to that needs some daemon to
write it. I.e. also needs some "configuration".
Finally, there is http://www.freedesktop.org/wiki/Software/xinput_calibrator
but it is n/a in Debian so I couldn't test it quickly.
