<pre>Also I found that restarting the device without i915 driver and then loading it
manually still works, even without those pins.
However if I do suspend even without i915, can't get anything except backlight
afterwards. Also if I disable suspend in BIOS it works fine then.
To me it looks like there is something either related to acpi management or
panel initialization sequence not mentioned in vbt is missing here.</pre>
