I can re-base the previously sent patch titled:
[PATCH] ACPI / video: Add systems that should favor native backlight interface
And put Mika's system into the DMI table that will use native backlight
interface in video module and remove it from video_detect's DMI table at
the same time. Does this sound OK?
