Even if core Mesa supports the OpenGL 2.1 API, the version reported by
glGetString(GL_VERSION) depends on the capabilities of the particular
driver that you're using. For example, if the driver does not support
GLSL, then OpenGL 2.x will not be advertised.
In the case of the i965, the i965 driver in Mesa 7.1 and later will
support GLSL. I _think_ version 2.0 or 2.1 will then be advertised for
i965.
