I did read the documentation that comes with FC-6 lm-sensors.
But as you say, it is not much help.

Unfortunately, /proc/acpi/thermal_zone is empty on this desktop computer
(Asus K8V-F Athlon 64)
even though I have compiled it into the kernel.
In fact that is true on all three of my desktops
(the other two being Sempron and PIII).
As far as I can see, this acpi entry is more or less restricted to laptops.

At least lm-sensors gives some response, even if it is incomprehensible ...
