The bottlenecks for POV-Ray that best fit into hardware are the same as for 
any other ray-tracer: The bounding. It is uniform and simple (for hardware) 
and can easily be solved in parallel. You can find various SIGGRAPH papers 
(early to mid 2000s) on real-time ray-tracing that also covered or 
referenced hardware BSP algorithm implementations.
