If you've got a newer Intel Processor it's because Ubuntu uses a new cpufreq driver called P-State. There are only two governors available for this driver, which are Performance and Powersave. There are no frequencies listed because you can't actually clock the processor to a specific frequency with newer Core processors.

One feature present in powernow-k8 that isn't present in acpi-cpufreq is support for enabling or disabling AMD's core performance boost technology.

CONFIG_GENERIC_CPUFREQ_CPU0=y. But it was not present in your previous reply. Can you confirm that the kernel config options I posted a couple posts ago are all that is necessary? In the third thread, I found this: "cpufreq" relies upon the regulator framework in order to change voltage. In turn, the regulator framework uses I2C0 to communicate to the PMIC.
