I inadvertently fixed it. The card insertion switch was damaged. Not exactly sure how, but mine is now permanently shorted (thinks a card is always inserted.) I don't know what side effect this will cause, it not knowing when a card is removed. But since I would probably not ever remove a card that is mounted, I can live with that.
