Maybe I should now also try to build CFQ (and the other schedulers, I
guess) as a module (instead of Fedora's default of builtin). That might
make it both easier and quicker to iterate over a number of ideas.

Does using the schedulers as modules require any handholding (on your
part, I'm afraid) or is it not really different from using any other
kernel module?
