It's the second one in the post with hibernation and suspend support.

Newest kernel, still the same problem.

Comment 7 lucas 2010-02-17 09:12:02 UTC 
I made a clean install with sidux 2009.4 (released 2009-12-31)

Which includes xserver-xorg-core 1.6.5

"# glxinfo |grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20090712 2009Q2 RC3"

Problem is reproducible by upgrading to xorg 1.7.4
(or just upgrading the system (apt-get update && apt-get dist-upgrade)
Upgrading the system brings me back to software rendering and the previously posted error message in Xorg.log

My temporary fix is to hold further xorg updates.
Comment 8 lucas 2010-02-17 14:04:01 UTC 
Updated test installation today and it works, same thing on production install. I'm not sure if it's xorg 1.7.5 or something else, but I'm happy.
