Change 21996 by marcel@marcel_nfs on 2002/12/05 21:31:16

	Recognize the DIG64 HCDP GUID. While here, dump the GUID if
	we don't recognize it. That way we have something to look
	for. For example: the Itanium prototype has an unknown
	table with GUID e18541cd-f755-4f73-928d-643c8a79b229. Alas,
	not the DIG64 HCDP table I'd hoped for, but then again we
	mostly want that for the HP box (which is running release,
	so I can't check right now :-)
