I'm not interested in vanilla kernel-power and, if I'm thinking about the same patch as you do, the patch won't work for kernel-bfs (as BFS doesn't support cgroups). I even doubt whether the patch will help kernel-power because of the way Nokia configured Maemo. All the features from kernel-power are also to be found in kernel-bfs (which include those you've named with the exception of the injection drivers, which aren't part of kernel-power either). F-cam drivers can be found on the garage page of kernel-bfs as well. As of now, kernel-bfs is a niche project; those who actively want to use it most likely will use it, but the vast majority sticks to the vanilla kernel(-power). Please read up on Con Kolivas. Also, use whatever you think suits you the best
