Hmm. I don't recall receiving any files, but it *has* been really pretty busy lately and I might have missed them.
Similar to Paul's effort, I find that for some images you just need to pull the shadows down with a Levels/Curves adjustment layer to push the noise into solid black. Here's an example ... I layered a Levels correction and a Curves correction on the left side image, you can compare it to the right hand one: http://homepage.mac.com/godders/IMGP3536.jpg Sometimes you can do the same with a simple S-curve adjustment using the Curves tool.
