SMSC SCH5627 Super I/O chips include complete hardware monitoring capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures.
The SMSC SCH5627 hardware monitoring part also contains an integrated watchdog. In order for this watchdog to function some motherboard specific initialization most be done by the BIOS, so if the watchdog is not enabled by the BIOS the sch5627 driver will not register a watchdog device.
The hardware monitoring part of the SMSC SCH5627 is accessed by talking through an embedded microcontroller. An application note describing the protocol for communicating with the microcontroller is available upon request. Please mail me if you want a copy.
