Fonts disappearing, artifacts and segfaults (redone)

[Michael v.Vierssen]

Hi,
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 ;)
