The smbus controller was designed for monitoring devices such as temperature and fan monitors. Since I've never been able to find any devices designed for the average use and the fact that is disabled by jumpers on many mobos, you shouldn't need a driver. There may be one on your mobo install disk but it's not necessary to install it as it does absolutely nothing even if the driver is installed and the smbus is enabled.
