I ran a 2.4.20 for several months (cannot remember which one). Decent
performance was only possible with every patch I could find (512M ram on
Duron 800).
I used a separate physical disk for capturing the audio, and suffered _severe_
problems with ext3 (corrupted partitions) which are not related to realtime
priorities.

I'm currently running 2.6.0_test10 (with Gentoo MM patches). Minimal setup
(JACK, Ardour, Muse, Fluidsynth * 2) produces no xruns (512M ram, Duron 1.2G)
