I've not used this one myself, so I can't guarantee how well it will work for you. A lot of people seem to like it however.

It can be found at a [KernelMirror|http://www.kernel.org/pub/linux/kernel/people/rml/preempt-kernel/v2.4/] near you. Most recent patch for the 2.4 series is for 2.4.26. The 2.6 kernel series already has pre-emptive kernel support .

I have used this patch on an HP Vectra (233 MHz P2, 32 MB RAM), to fix skipping mp3s when playing via XMMS locally, or XMMS remotely + ESD locally, and running remote X. This is a fairly slow machine by todays standards, and was seeing a lot of interrupt activity - lots of network, sound, and video changes. I would get nasty crackles in the mp3s if i changed virtual desktops and a large screen redraw was needed - the preempt patch fixed this.
