[Devkit8000] Touchscreen ADS7846 problem


I have a problem with my ADS7846 touchscreen. With new 2.6.38 kernel
(from http://gitorious.org/devkit8000/linux-omap-devkit8000)
touchscreen works only if I press on it, moving isn't work (I try
"cat /dev/input/event1"). However, all works fine with 2.6.28 kernel.

I have tried use old touchscreen driver (from 2.6.28 sources), but
when I touch my screen, Devkit8000 just hangs.

So, how can I solve my problem? Thanks in advance.
