There is little point in me filing a bug, as I have little information other than "{graphics,machine} locked up hard, reboot needed". I didn't notice any particular pattern to when it would happen. Any bug I'd file would have a low S/N ratio. I doubt I am only one seeing this with Nouveau, e.g., just from the last few months:

I don't think it is terribly controversial to say that 3D with Nouveau is less than super-stable. The driver is also blacklisted by Google Chromium for WebGL, for whatever that's worth (they seem to have a high bar though).

My solution for now is to use a desktop that exercises only the more mature, 2D parts of the graphics driver. I may give a GNOME shell / mutter based environment (i.e. Cinnamon) another go when I upgrade to F18, as it has a blacklist and (I gather) will fallback to soft-rendering (or can be made to).

You can set the environment variable LIBGL_ALWAYS_SOFTWARE to 1 to force fallback to software rendering.

Nouveau indeed is sometimes *really* unstable. It does not lock up hard though. E.g. numlock and so on works. Wait 30 seconds or so and it recovers. Wonder if you experience the same or not.

I noticed it is related to system resources somehow. Meaning: if I don't open too many tabs in Firefox, it is way more stable.

I'm a big Open Source advocate and whenever possible, I use and support such software. Sometimes it just doesn't work. I've encountered issues with the Nouveau driver in the past, particularly running programs under WINE. Try using the Nvidia driver. Fixed the problems I was encountering.
