Just talking with some other people with intel laptops who have similar 
issues, here's her xorg log:

http://pastebin.ca/1904990

Looks like it might be the same problem, the (WW) messages are very similar, 
mine just has some added info.

She also says a few more people happen to have the same crashes. And daily 
crashes, not weekly like mine.
