Yes, Ubuntu developers are trying to backport nouveau DRM as an ATI/Intel to .32 kernel and I think Debian can simply take their work. Because if not, 2 year cycle forbid us to use this driver in stable. And if mesa 7.7/7.8 hits the squeeze this pair (nouveau drm and nouveau dri) will be much useful. And if you also consider adding plymouth... hm my sweet dream! than this will be the best Desktop distribution ever.
