Subject: [PATCH] corruption checker: print the DMI board name

when the memory corruptor checker hits (as it has done now based on kerneloops.org data),
it would be extremely useful to know the DMI board name so we can add a blacklist for
such a machine... without having to ask the user for lots of extra info.
