W83697HF or VT8233 (or not?)

Your 83697 must be on the isa bus so you don't need
the CVS version of i2c-viapro to access it.
To force on the isa bus use the special bus number 9191:
'modprobe w83781d force_w83697hf=9191,0xXXX' where
XXX is probably 290 but check the output of sensors-detect
to see where it found it.
