coping to 2.6.28.NIT.03 didn't solve the problem. Gonna try to reflash the kernel to omap. [Added] With omap kernel it just hangs on the "booting - please wait". [added] LOL ok I was just stupid and copied omap kernel folder into 2.6.28.NIT.03 instead of running that command that MohammadAG wrote. xD So, calibration tool works now. Gonna restore xorg.conf and see if it works. Thanks for your help.
