    I suggest using libpng and libmng. I am not 100% sure, if they can read Fireworks. PNG chunks are quite difficult to understand.

    Hmm... I found from http://www.libpng.org/pub/png/src/pngcheck-2.3.0.CHANGELOG that pngcheck has support for mkBT and prVW. I am not even sure, what this is exactly, but I think that if pngcheck has support for mkBT, prVW maybe the latest versions of libpng also support it or if pngcheck has it, maybe you can check its sourcecode.
