Closing as this is a hardware limitation, not a bug.

Álmos, feel free to contact vdrift developers that they might provide some more
hw-friendly shaders if they want to support ATI R3xx/R4xx GPUs with shaders
enabled. I have also noticed they use GL_ARB_shader_texture_lod (the
texture2DLod function in the fragment shader) even though the extension is not
advertised by Mesa and the R3xx/R4xx hardware doesn't and cannot support it
