UBUNTU: SAUCE: (no-up) set /proc/acpi/video/*/DOS to 4 by default
BugLink: http://bugs.launchpad.net/bugs/458982
acpi_video_bus_start_devices() in drivers/acpi/video.c sets the default
ACPI DOS value to 0, which lets the OS handle toggling of display output
but still leaves the BIOS handling brightness levels automatically when
connecting/disconnecting AC.
We want the OS to handle both where possible, so a better default would
be to set this to 4.
This likely will regress systems using proprietary video drivers which
will need to change this setting back using the sysfs interfaces.
