I believe the kernel is now using the centrino_speedstep.c code. (I may be wrong with the file name) and it uses the cpufreq code to produce scaling. For Dynamic loading, there's cpudyn but I hear the new cpufreqd is better than cpudyn. I'm not sure if this answers your Q or if it was the correct thing to answer in the 1st place.
