The kernel offers a lvds output that does not exist. The mainboard (elitegroup ecs TIGT-I) does only have a VGA-out.The boot using video=LVDS-1:d seems to work. Don't know whether this influences "xserver-xorg-video-intel extreme bad performence on fullscreen (intel nm10 chipset)".
I am using debian testing, standard 3.1.0-1-amd64 kernel delivered via the debian testing repository.
