At any rate, could you try with commit 7ecc778691c452285f754743a93a46fa1d3da52f Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Tue Nov 4 10:36:26 2014 +0000 backlight: bl_power uses 0 for on and 4 for off The backlight/bl_power file didn't obey the obvious semantics, but instead operates using some interesting framebuffer API.
