I will send it to you off-list. I've been avoiding to publish it for a long time because the stock scheduler was *very* sensible to trivial attacks (freezes larger than 30s, impossible to log in). It's very basic, and I have no problem sending it to anyone who requests it, it's just that as long as some distros ship early 2.6 kernels I do not want it to appear on mailing list archives for anyone to grab it and annoy their admins for free.
Cheers, Willy
