Ok,

I've just tested this on my x2 5000, I did so with 2 loaded cores to also 
answer the questions about the 2 per core temps being pretty far apart when idle:

Loaded for about a minute:
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp:  +52.0°C
Core0 Temp:  +51.0°C
Core1 Temp:  +54.0°C
Core1 Temp:  +47.0°C

And after being loaded for some minutes:
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp:  +56.0°C
Core0 Temp:  +56.0°C
Core1 Temp:  +58.0°C
Core1 Temp:  +52.0°C


The readings loook much saner now then with the driver in 2.6.28 (the +21 
degrees helps!)

cpu revision info:
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 107
model name      : AMD Athlon(tm) 64 X2 Dual Core Processor 5000+
stepping        : 2

I also get:
k8temp 0000:00:18.3: Temperature readouts might be wrong - check erratum #141


Regards,

Hans
