But if I try > to unload the module, it says 'can't unload file: Device busy'. 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 --=-FRBmZeJSTxHweZjKUrqu Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEABECAAYFAklo4rQACgkQM4TrQ4qfROMdJwCfRqfgXqHv+kUS7nLZMdlWTdOy 3l0AnA863KFqmF+5awctPDBVLvkFVYRp =bbgH -----END PGP SIGNATURE----- --=-FRBmZeJSTxHweZjKUrqu--
