I'll assign that issue to libpng for now. The patch does not seem to solve the issue for me, but this is up to the libpng (upstream) maintainers.
I rebuilt the Debian libpng package with the patch in place and installed it into my test chroot, the pdftex binary is linked with the lib in that package. The consequential pdflatex runs still generate pdf files with different check sums.
