It's a good point, is there a way to associate the input event device
that sends coordinates with the way that you set its calibration?

Cleaning of touchscreen data in kernel itself violates nothing; before
the decimation in-kernel that we have now was done, there was a dumb and
inadequate 32-sample averaging action in-kernel anyway, followed by tslib.

Now the arrangements in kernel that are specific to the touchscreen
shipped give great data already, tslib seems needless.  If I understood
what Nelson is asking, it's just about removing tslib from inbetween the
input subsystem data and XGlamo.  Not -->

All of this other stuff just got invented on this thread: kernel
touchscreen filter stack has been discussed on kernel list several times.
