Yep, looks fine. The only think we might want to sprinkle about are checks for panel off so we can avoid visible corruption if we whack timing or fb stuff while the panel is on.

So, I'd like to know if we could unlock the panel registers on pre-PCH hardware as well at init time; that way I could remove the unlock code From intel_lvds_prepare too. Should it be possible to set the PANEL_UNLOCK_REGS bits for pre-PCH hardware without having the target off?
