glxgears shows only a black window on 855GM. Tested on HP NX5000 laptop. Used components are Intel Q3 release:
- xorg-server 1.5.2
- xf86-video-intel 2.5.0
- libdrm > 2.4.0 (commit a59ea02)
- Mesa 'intel-2008-q3' branch, commit 46921a5
Afer switching back to Mesa 7.2 glxgears works again.

Exactly the same issue with 865G.
