Debabilizer from equilibrium is a cross platform solution that will do this for you.
I also believe that you could set up a batch process in Photoshop that will do this as well.
I wonder if imagemagick will do it as a command line option on the whole directory
I will read documents, maybe I'll find something.
Also, I'd like to try Photoshop CS3. I wonder how can I work with animated GIFs in it?
