Stefan sent proper patches to get nouveau going on his GM206, which will make it into the next 4.0-rc. Here is a tree that is destined towards drm-fixes: http://cgit.freedesktop.org/nouveau/linux-2.6/log/?h=linux-4.0 Let us know if it makes the card work. (Definitely no acceleration without signed firmware for now though.)
