SiS 650/961 is an I2C bus master only; it has no builtin sensors.
For that chipset, do not load the sis5595.c chip driver.  You must
have some other sensors chip.

Are you using sensors and i2c version 2.7.0?  Are you sure there are no
conflicting (old) sensors libraries on your system?  Does sensors-detect
find anything else?  Does your notebook maker provide any clue in docs
or on web about what sensors chip is used?
