True, the new "Centrino" CPUs are equipped with a slightly different speedstep 
control model, but have in mind that the speedstep support was only of 
marginal importance in my patch, as clearly stated in the original post.

The main purpose of the patch is enabling deeper sleep mode in the idle loop, 
which is a completely independent feature from the speedstep. Furthermore, it 
should work across all -M pentium models in combination with ICH3 and ICH4 
chipsets. I'd be more than glad to hear some feedback on if and how that 
works for people out there...

If it's easy, then by all means go for it. Unfortunately I don't have any ICH2 
based systems available for testing, so I'm 100% sure I won't be implementing 
it myself.
