If you have the directory, but it is empty, then the module is
loaded, but it did not find any hardware it could monitor. The way I
understand it, if the BIOS ACPI code does not define how to access
the hardware, then loading the module does nothing. This is why you
have the asus_acpi, ibm_acpi, toshiba_acpi, and omnibook modules.
They provide another way to access the hardware, if your machine is
supported. The acpitool program knows how to access the settings of
the first 3 of those modules, and give you the information.

You can double check if you have the modules by running "modprobe
fan" or "modprobe thermal" as root. If it finds the modules, it will
return without an error message, but if you do not have them, it
will tell you that the module was not found.
