Pulled cpufreq from my kernel and it's working fine without it. This includes powerd doing its thing and a normal list of speed/energy values from 'sysctl dev.cpu.0'. 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 -- R.
