No, that's too simplified. In order to be able to compare a 40D to a 600D/D5100/A55 you need to scale down the results to the same 10mp. You won't do that in the real life, of course, but if you did the results of these current generation DSLRs would be at least comparable.

The EOS 600D, Nikon 5100 and Sonmy A55v actually are better than the Canon EOS 40D with high ISO noise performance, quite a bit better actually.
The 40D has a nicer view finder. It is bigger and brighter.
And it has a solid high-fps (frames per second) performance if you would desire that. And its body feels solid and has a meaty grip.
But for the rest, the 600D is "more". Higher possible resolution. Better high ISO performance. Live view with contrast AF and phase difference detect AF. Much better LCD. A very good implemented movie mode, if one would want to shoot video with a DSLR. A swivel-screen. More compact and lighter.
The Nikon D5100 is quite comparable to the Canon. It lacks mirror lock up, though, its live view implementation is not as refined. It does have faster contrast detect AF during live view, but no PD-AF. It also has that swivel screen and very good high ISO performance.
On the bottom of my list would be the A55v, for its bottom hinged screen, ghost lights appearing in night scenes with bright lights in it, the lcd view finder instead of optical viewfinder with the actual scene being cluttered with info and symbols where with the other cameras that info is outside of the image frame (i find the info in the frame very distracting when trying to judge composition/framing), the loss of texture in brighter and darker areas and so on. Then there is the bottom hinged screen and some other things... last on my list.
From your choices, I would rate them on my list:
1. Canon EOS 600D
2. Nikon D5100
3. Canon EOS 40D
4. Sony A55v.
