Ok, what i've found is the following:

after upgrading the nvidia GLX driver, a 
glxinfo gave me that 
GL_EXT_texture_env_combine is in:


---[lots of not-directly relevant info]
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: RIVA TNT2/AGP/SSE2
OpenGL version string: 1.3.1 NVIDIA 29.60

---[other info] ( the >><< are mine )


ok, but then i rebuild nel opengl 
driver,.. and apart from speeding stuff 
(before:0.5fps after:40fps) landscape is 
still missing..

then, just to check, i build mesa 4.0.3, 
which creates his own libGL.so.1.3.403 on 
/usr/local/lib, while Nvidia GLX has his 
libGL.so.1.0.2960 on /usr/lib ... from 
what i've seen of the link paths in the 
nelopengl driver i deduce that 
/usr/lib/libGL is whats is being used..

So, GLX by itself (from what glxinfo 
says) should provide the required 
extension, and the warning doesnt arise 
anymore, but that did not help to get the 
lanscape to show. Aurelien, maybe your 
Mesa libGL is overriding the Geforce one? 
if thats the case, i will try to replace 
the GLX one with the Mesa in /usr/lib...

Greetings,
