    [PATCH] avoid duplicate mode set in lvds
    
    xf86SetDesiredModes() already sets lvds to full mode. later when
    xf86CrtcScreenInit() initialized randr12, i830_lvds_set_property will
    recall xf86CrtcSetMode and set mode to full. This patch is to remove the
    duplication. In my test, this can save about 0.2 - 0.4s x startup time.
