I've checked with the BIOS teams further, and they indicated at the time
that this is enabled on those consumer systems, the hotkey should be
switched over to a mechanical key rather than a software key, so the
keyboard interface would not see this key.  The support in the BIOS to
turn on and off WMI would actually enable SMI hot key events instead
(which could then be serviced by dell-laptop).
