There are two separate issues here, which you are apparently mixing.
* The SiS south bridge itself doesn't include any sensors. It implements
an SMBus master. You need to get this one to work first. You say that
Linus loads the i2c-sis96x driver, which may or may not mean that it
works (SiS chips are very odd to identify, as can be seen with FanSpeed
too.) So, first of all, please do:
modprobe i2c-dev
i2cdetect -l
And see if there's an SMBus listed for the SiS chip. If it is, you can
additionally run i2cdetect on it to see if devices connected to the bus
are seen.
* The sensor chip itself is, in your case, connected to the SMBus. You
need a separate driver for it. This is not the right list to discuss
this though, please use the lm-sensors list instead.
