It would be interesting to compare to a 5D2 ... since I don't have one, can you loan me yours?!? ;-)
Seriously, any chance you (or someone else) can shoot the same 16 images I did (using the exact same settings) and I'll post-process and add to my site so you can do side-by-side comparisons?
I have Photoshop actions so I can work through in a repeatable fashion and fairly efficiently so we have a true apples-to-apples comparison.
So what I need is put any lens on (I used 17-55 EF-S) and set to Manual, F/16, 1/1000s, ISO 100.
Set to max quality RAW+JPEG, and turn Noise Reduction OFF - everything else default.
In a dark room with the lens cap on, shoot at ISO 100, 200, 400, 800, 1600, 3200, 6400, and 12800.
Turn Noise Reduction to MAX and reshoot those same eight frames.
Create a zip file of all of that (will be about 500 MBytes!) and use some sort of decent big file transfer service (Conrad sent me one RAW file using transferbigfiles which worked well - RapidShare SUCKS!)
This would be an interesting comparison!
P.S. Yohan: Nice spot on the vertical line on the 7D - I didn't notice that earlier - note sure what's up with that, but not easily seen on other images.

it's better to do this with no lens and may as well just use 1/8000th
some lenses do funky little alterations to rated ISOs when detected.
if you dig deep, at the lower ISO the 7D can show MAJOR vertical bands all across the image, worst looking banding i've ever seen.
