Ok, I did some more testing, and found out rather bogus values in evtest:
Input device name: "TSC2005 touchscreen" Supported events: Event type 0 (EV_SYN) Event type 1 (EV_KEY) Event code 330 (BTN_TOUCH) Event type 3 (EV_ABS) Event code 0 (ABS_X) Value 2514 Min 0 Max 0 Fuzz 4
Which made me go through the git logs, and these patches looked suspicious. After a revert... yes, touchscreen works as well as it worked before.

(It is impossible to revert just 3eea..)
Its funny... changelog complains about duplicated code.. then inserts 30 lines of code. Along with check that was not there before.
Maxime, can you suggest a fix? Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
