What is causing this Kernel Panic?

My first guess is your graphics chip and/or pci bus. I'll guess and say you don't monitor temps, but did you notice if your system was getting extremely hot? Just a guess.

 

Have an external HDD or other storage attached through USB?

 

I'm getting the same bunch of crashes, all seemingly related to "Preview" and the same Windowserver errors: Except I'm on a G5 Quad, with the following specs:

NOTE: Did you ever resolve this issue?

 

I'm having very similar panics, sometimes reporting intel gpu and sometimes nvidia. What's going on? It's the new i5.
