The posix.4 real time scheduling classes are supported in 2.0. Most
of the other posix.4 stuff requires real time signals, and doing that
would require too much change in the kernel to make so close to 2.0.
Hopefully you'll see it in 2.1. There was a BOF session at the Berlin
LinuxKongress where real time linux was discussed, btw.
Cheers,
