What does all these errors that the X11 Nouveau driver spews out in
my /var/log/message mean? They don't seem to do any harm but I was
wondering whether it might be having an impact on the driver's
performance? 

Nvidia chipset used: NV34M (GeForce Fx Go5200 w/ 64MB RAM)
xf86-video-nouveau: 0.0.16-pre20100807
nouveau-drm: 20100520 (20100811 only usable with 2.6.35, I'm still on 2.6.34)
Mesa not in use, this happens on starting X11. 

Regards,
Alex
