This is the same card I have. I don't think patching the Xserver to use a 16MB aperture for an 8MB card is a good idea. :) The 8M of memory is correctly detected, but 1K is reserved because of the hardware cursor, so the useable mem is 8191kB instead of 8192kB. At any rate, with front+back+depth buffers and 128 scanlines for pixmap cache, the current static allocation scheme doesn't allow for 1024x768 @ 24-bit depth. You can use 800x600 @ 24-bit depth or you can drop down to 16-bit depth. I'm working on a patch to allow using only AGP mem for textures, and using the mem remaining after front/back/depth buffer allocation for pixmap cache rather than a hardcoded 128 scanlines. This allows 1024x768 @ 24-bit depth. However, as Felix points out, 3D performance suffers quite a bit at 24-bit depth.
