SpeedStep is not working well on Q6600@3000 #15

What steps will reproduce the problem?

1. I'm running 10.5.5 on a Asus P5KR board with a Q6600@3000, I'm on
Overclocking condition.
2. I'm using the 9.2.0 kernel (Speedstep version)
3. I installed IntelEnhancedSpeedStep_1.4.5.kext and last SpeedStep.

My CPU can do 1596 MHz and 2394 MHz. I cannot get it to go 1596 MHz.
When using the SpeedStep GUI in "custom mode" nothing happens when I select
1596 MHz - it 
just stays at 2394.
When I try via sysctl, it doesn't work either. In Others operating system
the trottle is working well.

Thank you in advance for your help.

Please provide any additional information below.

Please turn on DebugMessages in the Info.plist, reload the kext and try to
reproduce the problem. Attach output of this command:
sudo dmesg | grep IntelEnhanced && sysctl hw.busfrequency && sysctl
machdep.cpu && uname -a
