I don't think Warner Bros even puts on other movie trailers on their discs. I really like it when they do it and I'm not even that upset by the disney when they are at the start of the disc.
The Matrix Reloaded/Revolutions trailer is on the DVD of the current issue of Movie FX DVD magazine (issue #6). It's also got trailers for Die Another Day, Daredevil, The Two Towers, Star Trek: Nemesis, and X2, among others, on the disc.
