I've contacted Titan and Matan, the maintainers of kernel-power. No response from Titan, and Matan said that he didn't feel it was right for him to give the project to Pali, since he (Matan) isn't really the "owner" of the project.

He suggested that Pali just start his own power kernel project in Garage (it isn't difficult), and then upload to the repos as power-kernel-pali or something.

That might be the best idea. I personally would like to see a more "generic" community kernel project that is run by a long-term community member who keeps the project open to patches from all quarters.
