I agree. It looks like vignetting to me also.

but I still don't think that the sole problem here is vignetting

Just that after perfect pre processing techniques he will still be left with the banded noise - odd that darks and bias didn't clean them up. I think he should borrow another DSLR and try it on the same setup to rule out a fault in his 400D.

The banding and colour noise will still be left - I would have thought bias frames would help but you're right - it could be an imager issue...
