Geert is right. Please update the patch to cope with module unloading. A hint: use devfs_mk_dir() to create the "fb" subdirectory first, and save the handle that is returned. Then when you unload the module, you can just unregister the handle and it will automatically unregister all the entries in /dev/fb/ Once this is done, it looks like your patch can go into my patch.
Regards,
Richard....
