[Bug 36345] Re: speedstep won't load on ThinkPad T20 and s30 (mobile coppermine Pentium 3)

I'm going to try to get you a kernel today compiled with cpufreq debug enabled so we can verify this. If it's the IST signature, then it's a hardware issue, in which you'll need to define the correct smi port and such.
