The driver must only reserve those ports on machines which needed them and when it needs them (which it never actually does). The ports are used for other superio related things on newer machines - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
