Oh ok, DeZionized combines 2 and 3 into one movie and removes Zion. That's the bulk of it. There are other changes, and in version 2 action scenes were trimmed to keep them from getting out of hand. The story on the whole remains intact, you just never see Zion. Further details here:

This edit (as outlined in the long drawn out first post) trims Zion but leaves a good deal of it. I removed anything that I found truly annoying or hurt what we know/loved about the first Matrix film. The Reloaded is trimmed mostly for ideas (there were no One's before Neo, he doesn't have powers in the Real World, etc.) and a few scenes of annoyance (the rave). It's still much shorter and ends at a different point so as to be more satisfying on its on (rather than such a silly cliffhanger (that feels contrived).)
Revolutions has been hacked up drastically (and as I've said many times is more a rough cut of what the movie could have been). I re-ordered events, changed the ending completely. (My father describes movies like the original version as "everyone ends up dead or miserable.") I wanted a more Matrix 1 like movie with an upbeat ending. I also explain the Oracle's change of appearance (using movie footage not the video game explanation).
If you want more details you can read the first post, but you should have the idea.

Dezionized put me on the path to this edit. It made me realize all was not lost and that it could be fixed.

Btw, it is available PiF and I am aware of a RapidShare release.
