Yes, I definitely think we should do this. Some sort of scanout buffer allocation will be minimally required for this new modesetting code to work. I'm still in the process of reviewing Thomas's (huge) TTM patch, which may get us most of the way there. > X could assume they > are just one big screen and the drm would deal with the translation > to the appropriate buffers.

I haven't thought it that far through yet, but it may be a possibility. I think X would still want to know about multiple screens though, since some applications may want to treat different screens specially (e.g. no IM popups on a presentation screen for example).
