cpufreqd didn't work for me because it first checks for the deprecated /proc layout to apply frequency changes instead of looking whether /sys/... was available. I think this should better go upstream instead of applying the patch. Reproducible: Always Steps to Reproduce:
Created attachment 26751 [details, diff] check-sysfs-first.patch just rearranged some code so that the check for sysfs comes first.
Created attachment 26752 [details, diff] cpufreqd-1.1.1.ebuild.patch
added patch 1.1.2-r1 and sent upstream, thanks :)
upstream said they'll add this patch in the next official release :)
