Yes, ureadahead needs an out-of-tree kernel patch to add trace events for open(), exec() and uselib() syscalls that take file paths. http://bugs.launchpad.net/bugs/462111 AFAICT, this never went upstream because upstream was discussing a generic approach of tracing any system calls, but I believe that never really panned out...
