I have a suspicion that this might have to do with the coretemp kernel
module, which would explain why it only seems to happen on fairly recent
Intel cpus. The documentation
(/usr/share/doc/kernel-doc-2.6.25/Documentation/hwmon/coretemp) says:
Supported chips:
* All Intel Core family
Prefix: 'coretemp'
CPUID: family 0x6, models 0xe, 0xf, 0x16, 0x17
Datasheet: Intel 64 and IA-32 Architectures Software Developer's Manual
Volume 3A: System Programming Guide

If anyone is seeing the same problem on non-Intel cpus (not mobos), then
coretemp is not the culprit. Anyone?
