Short of recreating your environment on 2005, or attaching that database to a 2005 server and upgrading it to compatibility level 90 , no, not that I know of.
Neither of the above is a trivial task, so they're not an option. Even if you did either, you would have to spend some time re-optimizing, reorganizing, etc... just to make sure that the database performance is up to snuff.

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?
