When I can't avoid referring to binary blobs in git, I put them in a separate repo and link them with submodules. It keeps the main repo trim and the whole thing fast while still giving me end-to-end integrity guarantees. I wrote https://github.com/polydawn/mdm/ https://github.com/polydawn/mdm/ to help with this. It goes a step further and puts each binary version in a separate root of history, which means you can pull down only what you need.
