There are aspects of the fb code that want changing for DRM (and indeed
modern hardware) but which won't break for other stuff. Given the move to
using main memory for video and the need for the OS to do buffer
management for framebuffers I suspect a move to DRM is pretty much
inevitable, along with having to fix the fb layer to cope with
discontiguous framebuffers.
