I just made test with MesaLib 10.2.6 and this version (also used and
tested with my hw in Free and newest Open) works fine. After simply 
replacement /usr/X11R7/lib/modules/dri/ by corresponding 
library from new Mesa my problems disappeared.

$ glxinfo | grep OpenGL
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Desktop
OpenGL version string: 3.0 Mesa 10.2.6
OpenGL shading language version string: 1.30

I knew rationales behind Mesa 7.x in NetBSD but - on the other hand
- support for newer GPUs may be worthwhile to consider...
