My T43 "works" with CPUFREQ, but behaves very strangely. Without it I see: dev.cpu.0.freq_levels: 2000/27000 1750/23625 1600/22600 1400/19775 1333/19666 1166/17207 1066/16733 932/14641 800/13800 700/12075 600/10350 500/8625 400/6900 300/5175 200/3450 100/1725 Without it, I no longer see any energy values (all show '0') and going on/off battery sometimes does not switch powerd properly. Also the system will automatically drop the maximum speed to 800 MHz when on battery. This all happens without cpufreq. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
