there's a lot of choices for which cpu & i/o scheduler to use, and it's not easy to switch between them.
come back when you can tell me what makes this patch better than the CFS or BFS, or why deadline / no-op is supposed to be good for flash memory. confused yet?

-edit-
deadline / noop is i/o scheduler, not cpu...
but my point is, you can swap them all around, it's not necessarily going to improve things.
CFQ is the default i/o scheduler for n900, palm pre, some versions of android...
BFS is used by some custom android roms, most distros use CFS though
