Can you try clearing the BIOS, don't run lm_sensors, but take a look at the ACPI in dmesg and /sys area, newer BIOS now report hardware monitoring through ACPI, which is a different ballgame. There was info about ACPI hw monitoring very recently either on this list or linux-kernel. Sorry cannot be more helpful. Out of cluebats today :( Grant.
