relevant part of syslog

Hi, 

X crashes (a few times per day), mostly when switching virtual desktops on NV4B
nouveau. I run debian testing  with nouveau git kernel and git
xf86-video-nouveau from the latest git. Most times the screen freezes and there
is no respondence from mouse-clicks or keyboard, but I can move the mouse.
Sysrq works. Sometimes X just crashes and restarts.

I did not observe this in October, so some early November commits
(unfortunately I did not check which one) must be the responsible.

I attach syslog and Xorg.log, if more is needed or testing required please let
me know. Thanks for your great work, cheers

Andi
