I may be wrong, but I thought this "exemption" wasn't required in the first place. DMCA 1201 applies to copyrighted material, and even then, only to measures that control access to the work. The Chamberlain v. Skylink case in the court of appeals for the Federal Circuit (which is binding in all other federal courts) established that the prohibitions can't apply to software the user is already entitled to use. The Court put it this way: "Consumers who purchase a product containing a copy of embedded software have the inherent legal right to use that copy of the software."
