chkconfig --list shows 'cpuspeed' running.
But I do not get the impression that it is working.
In februari 2004 there was a thread in fedora-testlist with respect to 'cpuspeed' because of the syslog boot error message. Then some user configuration was needed to get things working.
Furthermore the documentaion in the kernel-source directories, i.e. Documentation/cpu-freq hardly seems to be related to 'cpuspeed'.

There is a kernel module you have to bring in before it will work... for me it was p4-clockmod. Like you I went to the archives and found mainly posts from people saying to look in the archives.... how much better it is for future generations to answer the question and then say they should have looked in the archive. What I did in the end was go looking in /lib/modules for likely looking modules and modprobed them one by one until something good happened.
However - on my Inspiron 5150, I found it all pretty useless. Although it would idle to CPU down to 300MHz, and indeeed everything was correspondingly sluggish, this had no effect whatsoever on the (loud and intrusive) fan activity. So I assume much of the heat is coming from the video card / SDRAM and is constant no matter what the CPU rate. I turned it back on to "Performance" and forgot about it.

Thanks for the reply.
I had already looked in /lib/modules and found the following possibly relevant modules: acpi.ko, p4-clockmod.ko, powernow-k6.ko, speedstep-smi.ko
Indeed p4-clockmod.ko at face value seems to be the best bet for my Inspiron 8200 too. But I do not like trying things out if I can't find any solid documentation describing the workings.
Furthermore there is also a module cpufreq-powersave.ko. What is this one supposed to do and in what context?
The only documentation to be found is in the kernels-source directory with regard to cpufreq. This, with talk about 'governors' and things like that, does not seem to be relevant anymore and none of the above modules is mentioned.
If this is supposed to work on some pcs/laptops I hope it at least gets a mention in the release-notes when FC2 comes out!
ACPI also comes without any relevant documentation. Is this for the initiated only? You have to hunt all over the net for some docs and none describe in any detail how you can manipulate and use it.

It can get frustrating. The people who work on it know all the kinks, it can be a big effort to capture that working set of knowledge on a particular subject and write in down in a readable way.
Here's an idea, maybe Redhat (or Fedoranews, who already has a great tips section) or some other stakeholder should have a page of docs and stuff that is needed, people can register and 'lock' a subject for a couple of days, by which time they have to have submitted and had approved documentation for whatever it was they were interested in. Then they get a credit on the docs and the stuff is added to the official pile. Otherwise the subject comes back up again.
Even if nobody bid on the docs, at least there would be a public site tracking what was lacking. Anything that shows up on the mailing list twice, especially anything replied to with "search the list archives" should probably get added.
MySQL has a nice system too, eg
http://dev.mysql.com/doc/mysql/en/Date_and_time_functions.html
It is like a wiki without being uncool. It would be even better if an editor reviewed the comments occasionally and incorporated the good ones into the text (with credit), deleting those comments.
