Oh, right. So what exactly is the bug here? That the message appears
at all? Or is there another specific change that would cause the
warning to trigger once added? Or why do we have bugzilla entries for
broken hardware? Is there anything I can do to help the situation as
the owner of a machine which exhibits the problem?

Thanks for the info :-)
