I wondered if using GL_TEXTURE_CUBE_MAP would improve performance compared to rendering the 6 faces each time.
Having studied the lists of CubeMap issues, I could not find any example of such a cube actually being drawn.
I think you may be mistaken about what a cube map is. It's not a way of drawing cubes; it's a way of mapping points on something you're drawing to texture coordinates. One of the things it's useful for is drawing a far-away background such as a sky. You store an image of the sky as a cube map texture, and then draw a big cube around your scene. The cube map texture mode makes it render as though the faces of the cube were infinitely far away. The only relevance it has to rendering minecraft blocks is if you wanted to render reflections of the surroundings in the faces of the block, or something like that. Then you could use a cube map texture of the environment as part of the rendering process. But you still have to render the six faces of the cube as usual. There's no shortcut for that.
