Does not work, neither does saved_command_line, presumably because neither of them are exported (get "Unknown symbol in module" when loading the module)... linux/fs/proc/cmdline.c provides /proc/cmdline, and that just prints saved_command_line variable, but presumably it can use that variable since its not dynamically loaded kernel module.
