This is a bit old but it gives a basic outline. Worth reading the whole thing. It's short. http://forums.amd.com/devblog/blogpost.cfm?catid=317&threadid=99513 I'll have a wild guess that it might also allow a larger number of VMs. @ hoom Virtualbox 3 has "experimental" 3D acceleration. It was a bit flaky when I tried it but I only slammed it on 32bit Win' 7 for a look.
Alternatively, I can run Windows Vista/7 for games, and still have my flavor of linux running smoothly and with full 3d support (or at least good enough for doing basic development in opengl).
