ACPI _DOD is used to "enumerate all devices attached to display adapter"
and is used for output switching. This is used in acpi video driver but
I suspect actual feature is impact.  Especially, many laptop generates
super+p instead of ACPI event after Windows 7.

Please check with video switching hotkey works as expected. If so, this
can be ignored too.
