PNG premultiplied Alpha

Has anyone come up with a solution for exporting PNGs with premultiplied alpha?

SuperPNG used to do this in older versions by using the Photoshop alpha channel for transparency, but the new version appears to use layer transparency (much like Photoshop's PNG & Save For Web PNG export).

The old version also appears to be incompatible with CS3+
