The easy way is to think of the Kodak as a Drebel version of the 1Ds. Costs less yes, but just not as good.
The 1DM2 is a completely different beasty.
As mentioned the Kodak is a studio camera, it likes lots of light, which you can get in a studio. With lots of light, it will apparrently take really great pictures (which is why I keep looking at it for my next camera). However, outside of the studio, other then pixels I feel my 10D is better in the utility department. Shoots faster anyway and works in lower light, with less noise.
The Kodak will work out doors, but you will have a lot more work to do in the post processing phase.
The 1DM2 on the other hand is a sports camera, if you need to take action shots and in settings where the light is not so good, all my research says the 1DM2 is the one for you.
For me, The 1DM2 does not meet my needs, but most of the time I am shooting in a studio. The other critical part is the Kodak is a full-frame camera, good for artistic wide angle shots, while the 1DM2 stil has a FOV crop factor of 1.3x against it.
Finally, If you can afford the 1Ds go for that instead if you don't need the frame rate of the 1DM2. The only reason to get the 1DM2 if you can afford the 1Ds.
Just my semi-informed opinion.
For trivia; I tried to weasel a cheap Kodak SLRc out of my Kodak buds on their Government side (soon to be ITT maybe), but the ones I knew can't get one using their discount (they only get the discount on P&S cameras). Darn.
