I may have spoke too soon. About 90 minutes after sending this message, 
and after 1 hour+ of watching a flash video (a CISSP training course) I 
got a lockup which required me to power off my laptop. After fsck'ing I 
got back to my desktop, opened firefox, opened my flash video again, and 
it locked up almost instantly. This time I got a core though.

I'm not sure if this is related to the nvidia driver or not, but there 'tis:
