AGP is used for sending commands to the card, while textures and framebuffers (front, back, depth, each of the size of the screen) are in card memory. Assuming I can do math (not a given): 1024 x 768 x 4 x 3 / 1024^2 = 9MB for the buffers at 32bpp, leaving -1MB for textures :-) I think we've found the problem.
