Multitouch screen crashing Xorg

I have an Android tablet (Samsung galaxy note 10.1) and I try to make the touch screen work with the X server. I successfully set up the X server (after bringing down android's graphical server) inthe Arch linux chroot I use, but I can't get touch screen to work. I've tried all the drivers that are available in the AUR and in official repos (evdev, mutouch, evtouch, mtev, evdev-multitouch, multitouch, elographics). Appart from elographics and evdev the drivers did nothing. No input was found.
As about the elographics, I got a huge number of errors and just uninstall it.
Evdev, recognize the touchscreen as input, but when I touch the screen the X server just seg faults printing out some backtrace error messages.
The error messages in Xorg log from line 193 until the end, are generated when I touch the screen.

root / # xinput 
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Touchscreen0                              id=6    [slave  pointer  (2)]
⎜   ↳ Digitizer0                                id=7    [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Keys0                                     id=8    [slave  keyboard (3)]

The digitizer0 is the pen input (S-Pen). It's different from the touchscreen and works perfectly with evdev.

Here is my xorg.conf: https://gist.github.com/5219685
