Thanks for your report.  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.
