Why should Linux re-do all such things? Sure, there are a lot of things that the boot loader can use from the device tree, but I'm not sure if the LCD panel connection fits into the same category as the devices that Mark was thinking of. Anyway, display controllers are definitely something that needs to be handled in some way, which may or may not be the same way we handle more complex collections of arbitrary devices.
