Looking for a BVH packet traversal with frustum test back

Hello all,
so it seems that I only use this forum to ask things :/
Does anyone know a implementation for BVH raypack traversal that use also frustum tests?
Something as described in the "Large Ray Packets for Real-time Whitted Ray Tracing"
[LINK http://cseweb.ucsd.edu/~ravir/whitted.pdf]
Thanks in advance!
