Just figured that one out... Apparently, ATI's fglrx drivers suck as they are apparently missing a huge chunk from the 2.0 spec:
glBlendEquationSeparate glDrawBuffers glStencilOpSeparate glStencilFuncSeparate glStencilMaskSeparate glAttachShader glBindAttribLocation glCompileShader glCreateProgram glCreateShader glDeleteProgram glDeleteShader glDetachShader glDisableVertexAttribArray glEnableVertexAttribArray glGetActiveAttrib glGetActiveUniform glGetAttachedShaders glGetAttribLocation glGetProgramiv glGetProgramInfoLog glGetShaderiv glGetShaderInfoLog glGetShaderSource glGetUniformLocation glGetUniformfv glGetUniformiv glGetVertexAttribdv glGetVertexAttribfv glGetVertexAttribiv glGetVertexAttribPointerv glIsProgram glIsShader glLinkProgram glShaderSource glUseProgram glUniform1f glUniform2f glUniform3f glUniform4f glUniform1i glUniform2i glUniform3i glUniform4i glUniform1fv glUniform2fv glUniform3fv glUniform4fv glUniform1iv glUniform2iv glUniform3iv glUniform4iv glUniformMatrix2fv glUniformMatrix3fv glUniformMatrix4fv glValidateProgram glVertexAttrib1d glVertexAttrib1dv glVertexAttrib1f glVertexAttrib1fv glVertexAttrib1s glVertexAttrib1sv glVertexAttrib2d glVertexAttrib2dv glVertexAttrib2f glVertexAttrib2fv glVertexAttrib2s glVertexAttrib2sv glVertexAttrib3d glVertexAttrib3dv glVertexAttrib3f glVertexAttrib3fv glVertexAttrib3s glVertexAttrib3sv glVertexAttrib4Nbv glVertexAttrib4Niv glVertexAttrib4Nsv glVertexAttrib4Nub glVertexAttrib4Nubv glVertexAttrib4Nuiv glVertexAttrib4Nusv glVertexAttrib4bv glVertexAttrib4d glVertexAttrib4dv glVertexAttrib4f glVertexAttrib4fv glVertexAttrib4iv glVertexAttrib4s glVertexAttrib4sv glVertexAttrib4ubv glVertexAttrib4uiv glVertexAttrib4usv glVertexAttribPointer
That being said, is there a way to force GL to be pre 2.0 even though the driver says otherwise? This way I would still have ARB version of those objects...
One way to do this is obviously to hand-edit Base/glew.h and remove mention of the GL 2.0, but there perhaps should be a more "elegant" way with a configure flag (I am a total newb when it comes to editing configure scripts, though).
