I have fedora 18 and that program is working for me.
Maybe scour your dmesg output to see if a module is not loading?
I see stuff like this in mine:

[ 1.700949] powernow-k8: this CPU is not supported anymore, using acpi-cpufreq instead.
[ 1.702161] acpi-cpufreq: overriding BIOS provided _PSD data

When I run cpupower frequency-info I get:

CHECK IT OUT!!! (On a whim, I switched to overclocking my cpu, and cpupower didn't like that. The /sys directories are gone too.)

no or unknown cpufreq driver is active on this CPU
