Well, I should add that there is some unexplained difference between
OpenPandora and GTA04 when running this kernel on both. On the OpenPandora
the backlight is turned off by X11 screen blanking. While on the GTA04
it stays white. I.e. panel is shut down but not backlight. Although
/sys/class/backlight is available and works as expected. But we have
different backlight drivers and DT setup.
