dmesg with win8 patch and video.use_native_backlight=1

I tested the latest kernel on drm-intel-next-queued branch with the patch
applied and video.use_native_backlight=1 set in kernel cmdline. 
And there IS the directory acpi_video0 in /sys/class/backlight.

Do you mean that you want me to report this bug on bugzilla.kernel.org?
