Thanks for the idea, but running ' /sbin/lsmod | grep cpu' gives me this:

cpufreq_ondemand       10317  1
acpi_cpufreq                  12365  2

so acpi_cpufreq is loaded. I may need something else loaded, but not 
that I can find out.
Another thing I noticed is that on boot it says cpuspeed starts fine, 
but after stopping it and running '/usr/sbin/cpuspeed' I get this:

# /usr/sbin/cpuspeed
Error: No speed steps could be determined!
Error: No speed steps could be determined!

That might be a problem...
