Arch Linux on Paperwhite2

Hey guys,

I just managed to get Archlinux running in chroot on my paperwhite 2.
Now I am trying to set up xorg but for lack of experience i have no idea how to proceed ;)

I can run xapps like xeyes, xclock... but they use the already running kindle xserver.
When trying to start a xserver in chroot, I always get '(EE) no screens found(EE)'

I installed the fbdev driver, but i actually have no idea how to set the xorg.conf XD
Does anyone know how I could get the screen and multitouch running?
Or is there a way to start a 2nd xserver 'as an app' on top of the other one?

cheers
