The problem is simple: when setting up the AGP aperture, it's putting it after the framebuffer + CONFIG_APER_SIZE, which is wrong. On that guy, CONFIG_APER_SIZE might only be _half_ of the mapped vram space (as the card can be setup for 2 contiguous apertures). We need to make sure the DRM uses what is in MC_FB_LOCATION "top", and that itself should be set ideally to max(CONFIG_APER_SIZE*2,CONFIG_MEMSIZE) to avoid any possible kind of overlap.
