Thanks svdl, for turning me on to Gelato, that sounds like it has some promise!
I would love to speed up ALL my rendering, of course, not just Poser, but probably even more so my Lightwave (9.3)  and (eyeon) Fusion (5.3) renders... and they are high-end enough that I have some hope that Gelato plug-ins will appear eventually. Unfortunately, they aren't the most popular programs around.  That's the best part about the CPU approach is that everything becomes faster across the board, ...but those GPU based speeds are sounding irresistible!
