"gma500: address the lid code" triggers the lid code and hangs my non-LVDS system. This patch checks the sequence progress which according to any docs I can find should work. Unfortunately I cannot observe this on my device with LVDS because the panel comes up immediately. i915 never checks the sequence progress but instead retries for 1 sec but I rather not have that in gma500. If this turns out to be problematic, we can try doing the lid_timer_init right before gma_backlight_init which should only happen if we have a valid LVDS mode. Thanks Patrik
