Not sure if this one or 6/10 are needed. Originally we added lid
status support to detect LVDS presence and to reset modes if the BIOS
shut off planes/pipes at lid close time.
But neither of those was every very pretty, and the presence check was
a complete failure because every vendor has another, accurate way to
provide lid status; ACPI was only ever a red herring for us poor Linux
folks.
But if you have some good use case and we can get some really really
good test coverage, these patches look nice.
