Got it ... I'd like to wait on confirmation from LSI on this ... I
actually said the Megaraid3 wasn't 64 bit based on the 64 bit exception
table, but if it really has the firmware marker that says it's 64 bit,
we should make sure the manufacturers agree that it needs to be added to
the exception table.
