I can't seem to duplicate this error. Do you have any patches applied to 
the nvidia driver?

This patch does several things to allow the underlying hardware to be 
shared amount many devices. The most important thing is the use of
the created device via device_create instead of the hardware device. No 
longer should fbdev drivers use the xxx_set_drvdata with the parent
bus device. The second change is having a bus independent power management
for the framebuffer driver. The final change is using the release method 
to cleanup the device. The reason again is to make the fbdev driver 
independent of the bus parent device. Feedback is welcomed.

Causes an early crash on the powermac G5.
