new version of drivers/acpi/video.c has a feature to disable native backlight, but we wanna to 1) use native backlight or 2) make _OSI(Windows 2012) disable. Either is possible with current 12.04.05:

1) use_native_backlight backport was rejected by kernel team. The only solution is to use kernel parameter acpi_video=vendor
2) patch #5 was rejected.
