Alternative to Save for Web/Export as CSS Layers?

Question

I'm am SO DEVASTATED that CS6 got rid of the option to save as CSS layers in Save for Web.  I just updated from 5 to 6 and now I'm looking for an alternative but am having no luck.  I've tried some scripts I've found online but none of them work the way I need, or at all. 
I do animation in AI where each layer is a frame on the animation.  In CS5 I could Save for Web and check the Export as CSS Layers box.  This would export all the layers in my AI file to pngs, where each layer is it's own png file, in one folder.  I could then import them as an image sequence in Photoshop and turn layers on and off with each frame to create my animation.
I tried exporting my AI file to a PSD file with maximum editability but the more complicated the animation (meaning the more layers and the more objects on each layer) it would start flattening layers without warning.  Not to mention the rendering time just opening the file in Photoshop and then trying to save it there once I had created all my frames.  Photoshop froze on me 6 times this morning while I was trying things out.
I'm desperate for a simple way to do the CSS layer trick.  If I can't find one, I'm going to have to go back to CS5 permanently, or until I can find a solution.

here you go, let me know if it cuts it.
