No. This is not permission to relicense. This is permission to
combine. Each author still gets to enforce the terms of her own code.
So a tivoizer would have to take out the code licensed under the
GPLv3, and use only the code that permits tivoization. Same as today,
but without the possibility of cooperation for licensees who don't
tivoize.
Sorry if this wasn't obvious, it was for me.
