I have been playing with the values and I feel that I have made some 
progress.  Identifying the sensors is difficult as they all seem to show 
different patterns.

Under it87, temp1 is almost constant, it hovers around 26C, currently 
it's at 24C and I've seen it go as high as 27C.  Using stress (with all 
the different hogs), the temperature does climb, but not right away and 
this leads me to believe that this is indeed a sensor and it monitors 
the ambient/case temperature.

temp2 is a negative value and stays constant within a 3 degree range if 
set to a thermal diode, if set to thermistor it seems to stay constant 
at negative 55.  This is all throughout multiple stress runs, both 
memory, i/o, disk and CPU.  I'm assuming that this sensor is not connected.

temp3 swings wildly from -110 to about 108 degrees, and all over in 
between.  I've tried setting it as a thermistor or diode, and it still 
goes all over the place.  I'm wondering what I can do with this sensor 
as it's not really reading correctly.  It must be sensing something, as 
it does produce values all over the range, I'm just stumped as to what 
kind of compute function I would need to use to make this thing make any 
kind of sense.

I will further ask questions about the rest of the detected chips as I 
get to them, though I'd appreciate any thoughts on the above temperature 
sensors.

Thanks!
