First noticed when i tried to start cpupower service using s6-rc, it complains about a missing /etc/s6/config/cpupower.conf file and won't start, using pacman -Ql shows that cpupower-s6 doesn't provide that file
Running sudo touch /etc/s6/config/cpupower.conf should at least allow the service to start (if it has requires no environment variables).
The up script was reading the wrong path. It actually should have read /etc/default/cpupower which comes with the cpupower package. That has now been fixed and pushed. Thanks for the report. Just as a word of caution, using single quotes like in the example for "governor" won't work with execline. Double quotes or no quotes at all is what should be used.
