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
of /dev/input/event*.

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.
