-mga is probably also still relevant in some small number of cases. We 
can probably kill -cirrus. That would leave -openchrome, which I think 
is probably only really relevant for OLPC? What's the situation with the 
binary nvidia and amd drivers?

It's probably worth considering whether porting uvesafb to kms would be 
worthwhile, and then just using -modesetting.
