Actually I think we generally *don't* need to reset display.  It's
currently there just because we haven't tried reset handling without
it.  But not resetting display would make resets a little less visible,
which would be nice.  Now that you have a nice test setup, can you try
testing without the display engine bit set (i.e. only reset render and
media at hang time)?
