Cindy enable android PM in kernel config and build it.The android input subsystem accepts and interprets the x,y co-ordinates reported by the touch-driver (ads7846) properly if and only if the Power Management support is enabled in Android. Hence please enable CONFIG_PM while configuring the kernel for OMAP3 EVM.Then it myt work .
