At the moment there is no way to do this. I plan to add Geforce8 support to NVClock soon but it is not done yet.

Edit your xorg.conf and change (add one line) the following:
Code:
Section "Device"
    [...]

    Option "Coolbits" "1"

    [...]
EndSection
Then use nvidia-settings to change your clockfrequencies. That should do the job. Read here for more information about how to make the changes last when you restart etc.:

Nvidia-settings doesn't support overclocking of mobile hardware.

That's strange, because I also have a 8600M GT, and I have an option called Clock Frequencies right under GPU 0 - (GeForce 8600M GT) where I can adjust 2D- and 3D-clock frequencies (if I check the "Enable Overclocking"-checkbox).

You mean those settings won't make any difference? Huh, wierd..

You can use the NV-CONTROL interface to underclock mobile GPUs, only overclocking is disabled.

Are you planning to enable overclock in the next driver release?

No, I don't expect overclocking will be supported on notebooks (due to thermal constraints).

This is strange because my 8600M GT can support 8700M frequency without problem and without temperature increase respect original frequency.
