Log:
  MFC 270516:
  i915 driver - enable opregion handle; program CADL.

  add opregion handling for drm2 - which exposes some ACPI video configuration
  pieces that some Lenovo laptop models use to flesh out which video device
  to speak to.  This enables the brightness control in ACPI to work these
models.

  The CADL bits are also important - it's used to figure out which ACPI
  events to hook the brightness buttons into.  It doesn't yet seem to work
  for me, but it does for the OP.
