Technically no, pci/pci-e based cards don't need AGP. All of the Intel chips do, as they emulate AGP in all cases. The pci/pci-e radeons do not need AGP at all, but I don't know of a way to conditionally require the AGP module as a dependency in drm. The other issue would be that even if I could, it would probably end up with undefined symbols in drm without agp loaded, even if it isn't used. robert. > Roland
