[coreboot] Intel Doc reveals ACPI Laptop graphic functions

[Joseph Smith]

Hello,
Anyone interested in the quest for coreboot on a Intel Laptop may be
interested in this doc.

http://intellinuxgraphics.org/ACPI_IGD_OpRegion_%20Spec.pdf

It tells how to control laptop lids and blacklight control through ACPI as
well as other Intel graphics mysteries including the VBT, LVDS, tv-out,
etc. Just thought anyone looking to implement coreboot on an Intel Laptop
this would be a key tool.
