Incidentally I did try this hint, but presumably got the syntax wrong, so I went to the 9i docs at tahiti. Unfortunately this hint doesn't seem to appear where I'd expect it (in the access paths hints section for performance tuning.), or in a search. Did you find it elsewhere or is it time for a documentation bug.
