It kinda works on my GeForce 8200. And it's kinda broken.

While KMS works perfectly, from the console to logging into my Xfce desktop,
performance is pretty bad. Nowhere *near* as bad as the proprietary driver is,
but it's still definitely stuttering and slow in places while just doing 2D
desktop work. I haven't tried 3D games yet.

I checked my Xorg logs, and this is what I see:

(EE) NOUVEAU(0): Error creating GPU channel: -16
(EE) NOUVEAU(0): Error initialising acceleration.  Falling back to NoAccel
(==) NOUVEAU(0): Backing store disabled
(==) NOUVEAU(0): Silken mouse enabled
(II) NOUVEAU(0): NVEnterVT is called.
(**) NOUVEAU(0): DPMS enabled
(II) AIGLX: Screen 0 is not DRI2 capable
(II) AIGLX: Screen 0 is not DRI capable
(II) AIGLX: Loaded and initialized /usr/lib64/dri/swrast_dri.so
(II) GLX: Initialized DRISWRAST GL provider for screen 0

By far it looks like the biggest errors are in the EE lines, where it says it's
falling back to NoAccel. How can I fix that?

The other big problem is where it disables the backing store. Probably not good
for performance. And lastly, it tells me it's not capable of DRI/DRI2, even
though those are both installed and working correctly for my other (ATI) card.

I'm using:

kernel 2.6.33-rc7 (vanilla, straight from upstream)
mesa git (today's checkout)
libdrm git (today's checkout)
xorg-server 1.7.99.2
dri2proto 2.2
xf86-video-nouveau 0.0.15_pre20100213
nouveau-firmware 20091212


I will say that there is no documentation at all for which specific nVidia GPU
family my chipset belongs to -- only that it's "at least" nv50. The 8200 is
just a downclocked 8300, and the interwebs indicate that the 8300 (GS) is an
nv86 chip. So that's what I put in my kernel for the extra firmware:
nv86.ctxprog/ctxvals. Maybe this is screwing things up?

If I should actually be using the nv50 firmware, then lemme know -- I can
recompile. I just thought that it was for the old 8800 cards.
