Any update on this?

I'm experiencing the same issue. I even tried to install a newer
kernel via Squeeze backports with no success.

model name      : Intel(R) Atom(TM) CPU  330   @ 1.60GHz

Motherboard: Intel D945GCLF2

Adapter: ISA adapter
Core 0:       +7.0°C  (crit = +90.0°C)                  

Adapter: ISA adapter
Core 1:      +11.0°C  (crit = +90.0°C)                  

zoidberg ~ # cat /sys/devices/platform/coretemp.*/temp1_input

Linux zoidberg 2.6.38-bpo.2-686 #1 SMP Tue Jun 14 11:43:18 UTC 2011
i686 GNU/Linux

Same happens with current stable kernel (linux-image-2.6.32-5-686

Found a guy [0] who added an offset to sensors3.conf, but I don't know
if he knows what he's doing or it's just a lucky guess ;)

Ping me if you need more input.
