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.

I happened to look at an FC4 machine (i686 machine) and noted that
the kernel build configuration specified that the
CONFIG_ACPI_FAN
and
CONFIG_ACPI_THERMAL
as "y" rather than "m". I believe that this means that the code
for those "modules" has been made a part of the kernel itself
rather than as a "loadable module" from the /lib/modules/....
directory.
I am not very expert on kernel configurations, however, so perhaps
someone with more experience might comment on the correctness of
this statement.
I don't have the FC5 machine in front of me, so I am not sure
whether is has the same configuration.
