Yes, that will still work. However, without the cpufreq modules loaded by the
powersaved start script, your CPU might run at its lowest frequency all the
time (but this also depends on the BIOS etc).
OTOH it would be interesting to find out why powersaved uses so much CPU on
your machine. I am assuming that the machine just was idle for more than 10
seconds and powersave enabled throttling - which in turn causes all processes
to use _relatively_ more cpu.
You can check this with "cat /proc/acpi/processor/*/throttling", if it is
not at T0, the processor is throttled.
Of course, powersave de-throttles as soon as any cpu activity happens.
You can disable it permanently by setting ALLOW_THROTTLING="no" in all
schemes in /etc/powersave/scheme_*
Hope that helps,
Stefan
