Someone else had a similar problem with RH 8.0.94 (is that beta 3? or is that beta 4?) -- or at least, since you haven't actually given much real information (like the error message), I assume it was a similar problem.
According to what I guessed in that thread, RH changed their kernel again, so you need more than just this one patch. But I could be wrong, I don't run RH.
