AMD FX 4100, hwpstate0, powerd

[N V]

Hi.

I've got AMD FX-4100, ASUS M5A97, FreeBSD amd 9.0-RELEASE.
I've set
  hint.acpi_throttle.0.disabled="1"
  debug.hwpstate_verbose="1"

in /boot/loader.conf to eliminate acpi_throttle issues and to home more verbose output.

Also, I have
performance_cx_lowest="LOW"
economy_cx_lowest="LOW"
in /etc/rc.conf

If I try to enable powerd (via rc.conf) I get (parts of dmesg here):

Or if I manually launch powerd:

Is it something with BIOS and I can switch on/off something there, or is it something in FreeBSD and I can tune it, or is it something else?
