Hello,

These scaling problems are plaguing me on my Thinkpad T43 as well. The behaviour is very difficult to predict; sometimes it will scale fine on AC and battery power after a fresh boot, then begin to have problems on battery. Now it is failing to scale at all, even on AC power, on fresh boot.

My exact model is a 2668WMY, with a single core processor. (CPU details below)

I've also given the 2.6.32-22 phc kernel a try, and while it appeared to be helping at first, I'm now back to the unpredictable behaviour. I compiled and loaded the phc-intel module, and whlie I can now make the voltage adjustments, there's no help on the CPU scaling front.
