[Aus M2A-VM - Kubuntu Hardy - sensors v3] Wrong cpu temperature

[ticket]

Hi,

The issue : sensors give me strange/wrong CPU temperatures, especially k8temp.
I really don't know which ones to use or if any of these are exact.

My specs :

- Asus M2A-VM bios 2101 (last one)
- AMD Athlon(tm) Dual Core Processor 4450e 2.3 GHz
- Kubuntu Hardy Linux 2.6.24-19-generic x86_64
- sensors version 3.0.0 with libsensors version 3.0.0

Please attach the contents of /proc/cpuinfo. It is known that some K8 CPUs have broken thermal sensors, this is a hardware issue and there's nothing we can do.
