Yes, I can load it, but I'm unable to figure out what it is supposed to do,
or if it is doing anything.

No, not with just acpi-cpufreq loaded. With the help of Zwane, I've
discovered that if I unload acpi-cpufreq, I *can* load p4-clockmod, and then
the directory you mention appears, and I can configure governors, and life
is good. This all on 2.6.18-rc3.
Do I understand correctly that acpi-cpufreq is supposed to offer comparable
features?
Perhaps acpi-cpufreq *has* loaded, but did not find the proper hooks, but
has now registered itself, thus blocking p4-clockmod? When everything is
in-kernel, acpi-cpufreq might register itself first, which would lead to the
same thing.
For completeness, lspci. This is a desktop system, but I need some kind of
governer for quiet running.
