OpenGL Extensions

[windslip]

[GameClient][game_client.cpp(597)] Needed OpenGL extensions not found:

Texture Compression (GL_ARB_texture_compression)
S3TC textures (GL_EXT_texture_compression_s3tc)
S3TC textures (GL_S3_s3tc)


If you know your video card support this capabilities, 
try updating your video drivers to the last available version.
[Game][game_client.cpp(499)] Engine3D::Renderizer::get_active_renderizer()->finish_graphics_system()

(From error_log.txt)
When I try to start the game, that's what goes wrong.
I'm running Ubuntu 6.06 with a Radion 9250 graphics card. I have the latest drivers installed for the graphics card and have the OpenGL library updated. Does anyone know how to get the extensions?
