Running Fedora 19 with a live USB on an old system with Creative Labs Graphics

The first lines appear at boot. The second ones after a wakeup from S3.
However, other wakeup events (from S3 or S4) didn't show the same error.
Please
see my dmesg.txt attached to bug #68835 for the full output.

Could you also attach the Xorg.0.log file (should be in /var/log/) after you
see those errors, hopefully there's something in there too.

Xorg.0.log

Here is the Xorg.0.log captured after boot. I'm going to attach a new dmesg
output taken together with this Xorg.0.log, maybe it's easier understand
relationships between the two log files...

By the way, it shouldn't be in any kind related to this, however X starts at
1024x767 at 60 Hz, while my monitor supports up to 1280x1024 (which is its
native resolution) at a maximum refresh rate of 75 Hz (72 Hz and 60 Hz also
supported). Is this another (separate) problem?

I looked into this issue earlier, it looks like the NvNull object being
attached to the various DMA_NOTIFY methods of the relevant other objects.
Haven't had a chance to check if I also see this on my NV05 yet. That code
is
shared by all pre-nv50 cards though.
