have you really tested my last patch to be found under:
http://article.gmane.org/gmane.comp.handhelds.linux.kernel/3897
with num_xy_samples=1 and also num_z_samples=1?

Yes, for me too the pen detection could work faster. Don't know what to
improve further. The patch only uses one single reading for a sample. I can
do very small, fast dots in the draw pad and was never able to do those
accurate dots on the i in the hand writing tool but sure, I also have the
feeling that I have to press harder than before.

A further difference in the kernel (except the patches in ts-adc-debounce and
samcop-adc) seems to be that in contrary to former versions now the ADC
conversion is done interupt driven (in my poor understanding). Don't know if
this has changed anything concerning the above.
