If you search this topic, there have been others who are working with CI 2.0. But I'm not currently using 2.0 (and it isn't even officialy released yet, as far as I know — 1.7.2 is still on the home page).
I did add in some code that allows it to work with modules, however.
Finally, you shouldn't ever load in models manually when you are using DMZ. DMZ doesn't work with models the same way as CI.
