There is no "frustum" geometric primitive, so that would be hard.

You can kind-of do it by running six separate plane queries and running 
an intersection of the queries, but that's not very efficient -- less 
efficient than examining all nodes in order, in fact.

That being said: writing and debugging a quadtree for culling only is, 
what, five hours of work?
