CFS is not required at all, and so are cgroups. Any kernel with the BFS patch applied will run just fine on Fedora. In fact, most of the time I run a kernel using both BFS and the BFQ I/O-scheduler, on Fedora and Arch.
"CONFIG_CGROUPS (it is OK to disable all controllers)" is listed under "REQUIREMENTS" in the systemd README.
I don't know what the difference is between not compiling cgroup suppport into the kernel and compiling it in but disabling all controllers but it looks like that your assumption that cgroup support isn't required is wrong.
Well, here's a conundrum. Heinz uses it and it works, but the documentation says it shouldn't work. =><=
There must be some functionality disabled on Heinz' system. Gracefully disabled, or everything would crash.
Heinz, what does cat /proc/cgroups show?
