screenshot of glxgears

I'm using Gentoo -  amd64 profile. Kernel:
2.6.25-gentoo-r7 x86_64 Intel(R) Pentium(R) Dual CPU T2370 @ 1.73GHz
GenuineIntel GNU/Linux

I have a Lenovo N200 with a GM965 chipset (X3100 graphics). I tried lots of
different settings combinations in xorg.conf.

When accelerated rendering is enabled both glxinfo and glxgears give this
error:
"Failed to initialize TTM buffer manager.  Falling back to classic."

glxgears looks weird, is really slow (60 fps) and messes up everythin on the
same "height" (screenshot attached). The affected windows/parts-of-desktop are
redrawn after moving something on top of them etc. I've attached a screenshot.

Games tend to crash the system - besides the fact that I can't see much. The
system is unresponsive then but sometimes shuts down cleanly after I press the
power button.

(I'm not sure if it's critical but it does crash and hang...)

Reproducible: Always

Steps to Reproduce:
1. startx
2. run glxgears or some other accelerated app

Actual Results:  
It looks as on the screenshot. Affects other apps. Uses very little cpu (2%).

Expected Results:  
Should look normal and run faster.

That's the bug report on Gentoo's bugzilla:
