There's probably an issue with depth buffer precision and the
direction of the depth compare function.

Sounds like a problem with your setup. I get about 90 failures in Win
7 with an AMD card, with an nvidia card you should be getting
something like 25. What makes fixing tests difficult is that you need
to understand the failure before you mark something broken.
