Hi!

Which driver do you use? Is it speedstep-ich? If so, it's now available 
in vanilla kernel since... 2.6.16-rc1, slightly too bleding edge for 
common mortals but it means it's coming soon!

If you don't want to wait, you can just apply the 2 patches of Mattia 
Dongili on a 2.6.15. ("Move PMBASE..." and "Measure transition latency 
at driver initialization" _updated_)
