[lm-sensors] can't get tempurature readings!

Hi All

I have lm_sensors-2.8.7-2.40.3 installed, with kernel 2.6.9-11.ELsmp, 
installed on a CentOS 4.1 machine. sensors-detect seems to work fine, 
the modules it suggests are loading, but when I run sensors, the 
temperature readings are wrong!

The temperatures seem to be stuck at +127°C - and never waiver, very 
odd. My machine cannot be running that high! Also, 127 is kinda half of 
256, but that may be a coincidence. Still raises my suspicions that the 
reading is faulty somehow....

Here is the output of sensors :
