I know it shipped with some new Macs so some here might have an original CD bundle with it that they never noticed before. It would appear that my 9.0.4 CDs came with iMovie 1 and a 9.1 bundle came with iMovie 2.

As for locating a standalone disc I do not know where you would look for that(ebay can burn) unless you could request it on some "abanonware" site or something.. Taking into consideration any possible legal and moral ramifications as well.
