Most of the work here is software, and while we'd love to do this under
Linux, we haven't gotten there yet.

Ideally, we'd have hot-plug video card support and could add/remove them
on the fly. Making that work in the existing X server is a pile of new
code. Making that work with direct-rendered 3D seems like a much bigger
challenge...
