I have HyperThreading enabled...

Enabling "powerd" gave me this error message:

est1: <Enhanced SpeedStep Frequency Control> on cpu1
est: CPU supports Enhanced Speedstep, but is not recognized.

OK, I figured it out by myself. Added cpufreq_load="YES"
into /boot/loader.conf but got error:

est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0
cpu1: <ACPI CPU> on acpi0

It works or not, I run "openssl speed" and my CPU is fully loaded but
freq_levels shows me only 2450..
