However, since no one's said it already -- welcome to Nouveau! >>From the looks of it, you could bring up a full open-source stack with your patches (i.e. Xorg + nouveau DDX + mesa) and use PRIME to render stuff (assuming the actual display hw has an X ddx). Although I suspect that you're going to want to use your own drivers. Still a little curious if you've tried the open-source stack and whether it worked. [Not sure what the status is of render-node support is in mesa, but perhaps it's enough to try running piglit tests, if you can't get X going with the display HW.] -ilia
