What are the kernel messages you get when loading the modules? Try to load the module a second time after it had failed to load ... The problem should be reproducible at least with 340 as in the archive (and should be fixed in svn). Anything 361+ should not have the problem any more. Let me see if I can find my kernel log entries ... yep, that's * try to load the module -> nouveau already clained our device * try to load the module again -> proc_dir_entry 'driver/nvidia' already registered * access /proc/driver/nvidia -> OOPS (with jessie's kernel) [...] Feb 10 21:39:53 t530 kernel: [ 6.084133] [drm] Initialized nouveau 1.1.2 20120801 for 0000:01:00.0 on minor 1 Feb 10 21:39:53 t530 kernel: [ 6.123206] nvidia: module license 'NVIDIA' taints kernel.
