Fonts disappearing, artifacts and segfaults (redone)

I've done the following:
- Using the NV driver instead of the closed NVidia driver.
Not tainting the kernel in any way and 3D acceleration disabled.
- Getting a backtrace of Metacity segfaulting. See links.
The crashes and artifacts (see quoted message below) still occur :(
Please see the following links:
Could it be the hardware? And where should I look next?
Thank you ;)
