Hi,

I'm quite new to ZS, however I'm using it since week right now and everything is working great, 2.0 RC1.

Runnig in on netbook Samsung NC10, which has quite nice power management an can stay on battery quite long. However looks like ZS 2.0RC1 kernel lack the CPUFreq and corresponding cpu scalling governor, from dmesg:
[ 235.135116] Consider compiling CPUfreq support into your kernel.

For now this small laptop is running on full speed @1.6GHz, which is making him quite hot.
Is there a way to publish CPU scalling kernel modules like:
acpi-cpufreq
cpufreq_ondemand
cpufreq_userspace
cpufreq_conservative
cpufreq_powersave

Or post new kernel to use, then as result will be simple to script'ize the paths like: /sys/devices/system/cpu/cpu0/cpufreq/

Or maybe just pass the 'ondemand' governor to kernel argument?

[Edit:]
Or maybe just provide kernel sources for 3.4.6-ZS (and default cfg)
then I could recompile by myself.

Best Regards,
Gregory Very Happy
