Is your symlink correct? Sometimes I forget about that and it trips me up. What is the specific error you are getting when attempting to emerge powerdevil?

kernel symlink? yes it is correct, still how is that got to do with the problem?
powerdevil emerges fine without any problems, the problem is that it detects no cpu scaling support.
it was working before

That can easily cause problems if the kernel you are symlinked to does not have scaling support enabled when compiling against the kernel. It wasn't clear from your initial post whether this was a compilation issue or a runtime issue. I've seen similar errors when attempting to compile frequency scaling userspace utilities against a non-frequency scaling enabled kernel.

note this from my original post
Code:
dagg@NCC-5001-D ~ $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors                     
conservative userspace powersave ondemand performance


the question is, how can I solve it?
