Re: Re: [Dri-devel] Re: [Linux-fbdev-devel] Redesign of kernel graphics interface

It's not just bloat, the network code is used millions of times per second. Mode
setting happens occaisonally. 

The other problem is memory management. What is going to happen when fbdev
starts setting the mode for both heads? Who is going to mananage the VRAM when
the buffers get resized? OpenGL has a very complex memory management scheme
where things can migrate from VRAM to AGP to system memory.
