The problem is agpgart increases reference count of hw driver to prevent it from being unloaded, and the hw driver references agpgart so agpgart can't be unloaded either. Should agpgart be split into 2 parts, one (which would have to be unloaded first) managing the thing and the other - the library referenced by hw drivers? I wouldn't write about this but there is code to unload them so I think it's not intentional. -- Krzysztof Halasa
