Doesn't matter, because the runtime library is not under GPLv3. It's under GPLv3 plus the runtime restriction. That combination is more permissive than GPLv2 (because of the exceptions it makes). Therefore, as far as I can tell, there is no conflict; the combined program has no restrictions beyond the GPLv2 restrictions. In particular, the DRM rules don't apply; the more restrictive rules on patents don't apply. Unless you can identify a specific restriction that isn't waived by the runtime exception license, then I don't see the problem.
