general
Linux supports Dynamic Frequency Scaling for ThinkPads with mobile Pentium III, Pentium 4 and Pentium M processors.
configuring the kernel

2.6 kernels

If you have a Coppermine-piix-smi based Thinkpads like from the A2x, X2x and T2x series you might want to look at this page.
If you have a p4-class celeron based Thinkpad like the R40e you might want to look at this page
If you have a ThinkPad T23 load the following hardware specific module:
* speedstep-ich
Since 2.6.10, there is the ondemand governor in the kernel, which replaces any userspace daemon for cpu scaling and works very well.
configuring SpeedStep daemons
To use any of the following user space frequency scaling daemons you need to load the module:
- cpufreq-userspace
There are plenty of userspace frequency scaling daemons available:
