I have been working on a feedback multilevel scheduler with 40 levels to make it easier to incorporate with the kernel and user utilities. I haven't touched it for a while, but it was starting to work, but kept running into problems remoing things from the run queue. I had ambitions at one time of making it a tunable scheduler, but I'm still focusing on stability for now. I can probably generate some patches against 2.0.33 if there's interest.
