I am hoping you found this out by now, but in the replies he explains where to find it a little more:

Re: Frustum Culling Code ... I'm not going to post actual code, since this is a public blog. However, if you read frustrumCuller.h then the following, you should get it:

At the beginning of your renderObject method call init and pass it your SceneState

When you want to test if something is visible, pass testBoxVisibility a box (in object space), what clip planes you want to test against, and a zero. It returns -1 if the box is completely outside the view frustum, or a bitmask for what planes it hit.

If you still don't get it, go and read the source, it's pretty simple ;)
