Intel driver bugs

[Mateusz Kaduk]

Hi,
I refreshed my installation as You suggested and you were right some old
files in /usr/local were interfering with new one from git.
But now I still see some old problems which were reported not only by me.

The problems are

   1. Random freezes when "faling back to classic mode", EXA with non GEM
   enabled kernels
   2. Not working GLSL in any case
      - When I run Ethernal Lands and reflections are enabled game crash and
      I get
      [08:54:40] EXTENDED EXCEPTION(5:opengl_error): Error: 'Max instruction
      count exceeded' in file 'shaders/anim.vert' in load_vertex_program at
      actor_init.cpp (line 159). However turning off reflection helps
      - Nexuiz enabling GLSL and runnig game freez system
      - Sauerbraten enabling GLSL cause strange negative colors
      - Savage2 which requires shaders to run, renders white not textured
      objects
   3. Sometimes when screensaver turns off monitor its not possible to turn
   it back on by any key or mouse, restart needed
   4. In X switching to terminal and back with ctrl+alt+f? works but when
   You run any OpenGL full screen application then you can switch to terminal
   and switching back to X cause not reversable black screen, restart needed.
   5. I experienced also random freezes with UXA, but I doubt debian's xorg
   version 1.5.2 is aware of using dri2 so I stick to EXA.

Configuration is
kernel vanilla 2.6.26 and git eric's 2.6.27
Xorg 1.5.2 from debian (sid)
libdrm master
mesa master
xf86-video-intel master
dri2proto master

I would like also to point out that GLSL is not only requited for games but
latest blender is using it for realtime rendering. And they stated on their
page that "Intel or VIA graphics cards, ATI Radeon cards older then the Xx00
series, and Nvidia Geforce cards olderthan the 6x00 series are unlikely to
support this functionality well, unless through a slow software fallback"

Is there any chance to change this ? My card is GM965 and it has full
hardware support for OpenGL 2.1 but only on Windows.
