What exactly happens if one of these is not usable? I know that Darwin broke on the _PR description quite badly, as it just allocates possible execution engines using the ACPI Processor specification and I do not know what happens if the engine is not available. I have to admit that I have not tested it as I do not have the time to do so though, so maybe it works. I just read patch 13 ... nevermind
