From: Andreas Herrmann <andreas.herrmann3@xxxxxxx>
Reported temperature for ASB1 CPUs is too high.
Add ASB1 CPU revisions (these are also non-desktop variants) to the
list of CPUs for which the temperature fixup is not required.
Example: (from LENOVO ThinkPad Edge 13, 01972NG, system was idle)
Current kernel reports
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +74.0°C
Core0 Temp: +70.0°C
Core1 Temp: +69.0°C
Core1 Temp: +70.0°C
With this patch I have
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +54.0°C
Core0 Temp: +51.0°C
Core1 Temp: +48.0°C
Core1 Temp: +49.0°C

I think this patch should go into .35.
Patch was built against Linus' git v2.6.35-rc3-3-g9a3cde2.
(Hope that there is no conflict with your recent fix for single core
CPUs.)
Thanks,
Andreas
