In order to disable powernow, you shouldn't load the cpufreq kernel module, or don't compile your kernel with the device cpufreq. The cpufreq.ko is a bundlle of different hw drivers related to cpufreq, but without the acpi specfic ones, those being acpi_throttle and acpi_perf and they are included into acpi.ko. After that check, you want to go back to powernow enabled and without acpi_throttle, since powernow ofer way much more power saving than throttling.
