[lm-sensors] Funky temperature readings

[Per Jessen]

I've got a new Gigabyte board with the AMD 790FX chipset and an AMD Phenom quad-core CPU.  

After having loaded it87, I get three temperature readings - but the  BIOS itself 
is only showing two.  Is this "normal" ?  The third temp reading is quite 
high - usually 84-86C.
