This has always been the case. On my T30 which was a P4-M at, the lowest speeds available with P4TCC available was 75 or 100 MHz and setting my speed to either of the two lowest values would lock the system. I patched powerd to prevent either of these from being selected and everything worked form that point. That was a MUCH older version of powerd (at least from early last year) and I no longer have the T30. My new T43 seems to not have this problem. It runs flawlessly at all speeds, whether I enable EST (cpufreq) or not. The system clearly does better with cpufreq than without, but it falsely reports CPU speed with cpufreq. -- R.
