Try running a CPU-intensive task while you do something that requires real time operation, and see if the patch helps. As a quick test: a kernel compilation, and watching a movie in mplayer with frame dropping disabled. I get "Your system is too SLOW to play this!" all the time, and that is with desktop preemption enabled. The kernel compilation itself should be faster if CPU time is shared more effectively between tasks, I think.
Another one: run a CPU-hogging task (such as this, but
openssl speed should be enough) and a kernel compilation; time should be divided evenly between them. Something else which requires high interactivity: ab (apache benchmark) against your own machine. For the ultimate test: run kernel compilation, openssl speed, ab and mplayer in parallel and see how they fight it out.
