Patch Set 1: Code-Review+2

I'm OK with the change.  However I'd convinced Nick to put it the way it was in CB:45055 in case a new did became unreserved, i.e. it looks like the reserved values are merely unused, not unsupportable.  Since we're reading what's already in the register, I'd err on the side of interpreting it if possible.  (And an error message is OK too.)
