just apply the patch to 2.6.11-rc2 and you should be able to run e.g.
"jackd -R" as an unprivileged user.
This is a far better idea from an API perspective. We can continue
writing to the POSIX realtime standard interfaces. Yet users can
actually take advantage of them. I like it.
This still doesn't solve your privlige problem though. If I can't
renice something as a regular user, it makes no sense to allow such
realtime behaviour.
I still think the ulimit patches aren't a bad idea to solve your
privilege problem. At that point, is there still a need for
rt_cpu_limit?
