It is not enough to replace the kernel. You have to set ro.sw.hwrotation to "0" (in init.rc / ramdisk). Otherwise it won't work.

Now I can send events to kernel to change touch rotation (I'm using adb shell):

sendevent /dev/input/event2 17 1 0 -> portrait
sendevent /dev/input/event2 17 1 1 -> landscape
sendevent /dev/input/event2 17 1 2 -> portrait (reversed)
sendevent /dev/input/event2 17 1 3 -> landscape (reversed)

We only need an Android app that will do it automatically.

You are the best. I'll try it. Thanks a million.
