Yep, just like that. The thing I don't understand is

[drm] nouveau 0000:01:00.0: PGRAPH - ERROR nsource: LIMIT_COLOR nstatus:
BAD_ARGUMENT PROTECTION_FAULT
[drm] nouveau 0000:01:00.0: PGRAPH - ch 3 (0x0007b000) subc 7 class 0x4097 mthd
0x1d6c data 0x00000000

method 0x1d6c is used for fencing within the nv30 gallium driver. It always
writes a 0 to that method, so... I don't know what's going on. I'm not really
familiar with the hardware, I was just following code paths around and noticed
the user_priv thing causing the crash.

The other patch (to disable ARB_framebuffer_object) is also required since the
hardware can't handle it in all cases. The driver could work around it, but
that extension isn't required until opengl 3.0 which can't be supported anyways
(I'm told).
