I think steam would have to have a general Linux support. If they did, then I'm sure you could compile a few things and get it working correctly. Most games have a specific set of platforms that they can run on (which I'm sure you're aware of). There is no doubt that you could write your own emulator though.

But FreeBSD is not Linux though, it's well.. FreeBSD. But since since both Linux and BSD are posix compliant I guess the main issue is updating libraries and drivers, I know that they have Nvidia drivers.
