Still not found any solution, but as I can see with i810switch, the internal 
display get's deactivated through xrandr --output LVDS --left-of VGA. 
i810switch tells me, that CRT (the ext. output) is activated, while lcd is 
deactivated after executing the xrandr-command.

When I try to change the crtc with xrandr --output LVDS --crtc 0 X crashes.
