Stallman has a post about his Thinkpad X60, one of the very few laptops where you can install a totally open BIOS.
The Librem laptop was another attempt at this, but it failed pretty badly. They couldn't get around a lot of the "binary blob" issues with modern hardware. They're attempt may in fact show that truly open firmware on modern x86_64/amd64 machines may be impossible.
There's Novena, but I believe that's ARM based (which is possibly the best bet for truly open hardware today)
