Woops, sorry - typo. I meant 5870 (Apple provided). As far as I know, I'm not running any 3rd party drivers. The only non-Apple kernel extensions loaded are Parallels, which I've unloaded (and the problem persisted).
I should also mention, the Apple Hardware Test passes the machine.
I'll check out those two forums and see if I can find anything. Thanks for the advice!
Edit: The whole panic log is...

It varies slightly (sometimes some extensions are unloaded, sometimes not). The BSD process name changes almost every time; anything from Window Server to Mail.
