lm_sensors and wrong values on MSI MS-6704 (845PE Max2 FIR)

Thank you very much for your feedback. I also thought
that sensors-detect failed to properly handle
my system (I am using sensors version 2.6.5).

Looking in the manual there was a reference to
w83627hf in one image, but the chip was reported
as not installed by sensors-detect...

The solution I have found was to try the isa bus.
So, I manually loaded i2c-isa, and then
modprobe w83781d force_w83627hf.
And magically everything worked!
sensors gives output like:

w83627hf-isa-0290
Adapter: ISA adapter
Algorithm: ISA algorithm
VCore 1:   +1.48 V  (min =  +1.37 V, max =  +1.52 V)       ALARM
VCore 2:   +1.50 V  (min =  +1.37 V, max =  +1.52 V)
+3.3V:     +3.23 V  (min =  +3.13 V, max =  +3.45 V)
+5V:       +5.02 V  (min =  +4.72 V, max =  +5.24 V)
+12V:     +11.86 V  (min = +10.79 V, max = +13.19 V)
-12V:     -11.98 V  (min = -13.21 V, max = -10.90 V)
-5V:       -4.95 V  (min =  -5.26 V, max =  -4.76 V)
V5SB:      +5.53 V  (min =  +4.72 V, max =  +5.24 V)
VBat:      +3.05 V  (min =  +2.40 V, max =  +3.60 V)
fan1:     2596 RPM  (min =    0 RPM, div = 4)
fan2:     1906 RPM  (min =    0 RPM, div = 4)
fan3:     5357 RPM  (min =    0 RPM, div = 4)
temp1:       +23C  (limit =  +60C)                       sensor = thermistor
temp2:     +59.0C  (limit =  +60C, hysteresis =  +50C) sensor = 
PII/Celeron diode   ALARM
temp3:     +44.5C  (limit =  +60C, hysteresis =  +50C) sensor = thermistor
vid:      +1.450 V
alarms:   Chassis intrusion detection                      ALARM
beep_enable:
          Sound alarm disabled

The only problem I had was with the fan speeds, where the two first
fans always reported 0RPM, but I got it working by setting the
divider to 4. I addionally installed ksensors, and everything
is fine...

BTW, is my systems configuration so peculiar that
sensors-detect failed to configure it?
