hpet is a hardware timer included on most machines since 2005 (http://en.wikipedia.org/wiki/High_Precision_Event_Timer)
This is generally what I use. You may also want to disable frequency scaling as I have noticed that xruns seem to occur when the CPU changes frequencies. There should be an applet for that (there was under Gnome). I use KDE which does not seem to have such an applet, so I wrote a quick little script to handle that. I also assume that you meant that you have already installed and tweaked rtirq?
