I too am having this problem, though I can ssh into my box. Since it kicked in when I ran KeyShot2 (opengl), my hunch is that it is graphics card related. In fact, I'm tempted to believe that its switched rendering to the other graphics card, but continues to display the first.
This is an interesting theory.
I've read about excessive thermal paste found by ifixit. They said, +"Holy thermal paste! Time will tell if the gobs of thermal paste applied to the CPU and GPU will cause overheating issues down the road".+
I've experienced several lockups, some with racing fans and some without. Most of them happened upon waking from sleeping overnight or connecting/disconnecting a display. Some have happened when connecting or disconnecting USB keyboard/keypad though.
If this is as you suggest, I am even more concerned because I have automatic graphics switching turned off. It was one of the first things I did even before transferring apps. So maybe it's the AMD graphics chipset/driver that is the problem.
I've stopped Mac Scan's nightly scanning. Since then the MBP has been responsive in the morning. I have also stopped using my Logitech G-13. I disconnected this yesterday and have not seen a lockup since. I run VMware daily (even some lightweight compiling) and have been watching video (iTunes, Hulu & Netflix) and playing dragon age 2 with no problems...
I'm going to run some CPU-intensive ops to see what happens. I'm
planning to boot in single-user mode to do this. That should exclude graphics switching and all but the basic driver. I'll post details if I can repro in single-user mode.
