Thank you, it really helps, now after boot I always get valid 1.7Ghz as
high possible CPU speed.

but sysctl picture changed:
now I have:
% sysctl dev.cpufreq dev.cpu dev.p4tcc dev.acpi_throttle
dev.cpufreq.0.%driver: cpufreq
dev.cpufreq.0.%parent: cpu0
dev.cpu.0.%desc: ACPI CPU
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=3D\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=3Dnone _UID=3D0
dev.cpu.0.%parent: acpi0
dev.cpu.0.freq: 1487
dev.cpu.0.freq_levels: 1700/-1 1487/-1 1400/-1 1225/-1 1200/-1 1050/-1 1000=
/-1 875/-1 800/-1 700/-1 600/-1 525/-1 450/-1 375/-1 300/-1 225/-1 150/-1 7=
5/-1
dev.p4tcc.0.%desc: CPU Frequency Thermal Control
dev.p4tcc.0.%driver: p4tcc
dev.p4tcc.0.%parent: cpu0
dev.p4tcc.0.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1 3750/-1=
 2500/-1 1250/-1
sysctl: unknown oid 'dev.acpi_throttle'
%

so I've lost dev.acpi_throttle and got dev.p4tcc. Is it right ?

powerd still works as expected.
