I just tested my Dell T1600 tower with Quadro 600 graphics under both 7.99.59 and 8.99.6 (from the 7th of November). Both work fine with dri and whatever 3D acceleration nouveau provides (my usual test is glxgears - to keep the same fps no matter the size of the window).
I also have similarly working ThinkPad T61p with Quadro 570M, working fine as far as the graphics is concerned.
None of these is new enough, though. I am about to test the live system on my HP Envy with both Intel HD 530 and GeForce 950M, and I am pretty sure it will not work as before. I will confirm later.
