I was curious enough to track this down. Support for "per-task per-cpu" counters wasn't added until the 2.6.33 kernel, specifically changeset f4c4176f21533e22bcc292030da72bcfa105f5b8 Before that access with task_cpu required root and would always return 0. Unfortunately there's not much that can be done about it except run on a newer kernel.
