I think that seems reasonable, but you're the ACPI expert.
As long as the patches on list:
 * can be reviewed by somebody for whether their ACPI changes
   are correct, including whether the golden-master changes are right
 * can be applied by a maintainer without having to do anything
   special
 * don't break bisection

then I'm happy. It sounds like those steps will work for that.

You have a stray submodule update in your patch, though :-)
