Only thing I've heard of is the alpha build of Alky project. Very bold project that is attempting to create a program(s) that will modify the API of a DX10 game, to run on the SDK of DX10, on a multitude of operating systems.. I was prompted to check the site, to give you any new news, but the server seems to be down.. Whether temporarily or otherwise, it's disheartening news.
Here's an Ars technica article on them,

I dunno of anything similar going on though.
