Thanks for catching that. As Hector is changing that entry he can hopefully take care of it. Regards, Arend

This chip exists in two revisions (B2=r3 and B3=r4) on different platforms, and was added without regard to doing proper firmware selection or differentiating between them. Fix this to have proper per-revision firmwares and support Apple NVRAM selection.
