Here is a couple of samples from a Demo version of a program called Grain Surgery that I just downloaded. (I have included a link for anyone interested)

This first image is a photo that Niko uploaded the other day called Kid. The grain (actually dye clouds because it is color) is very strong. I asked what film was used,but as Niko is never around on the weekends I have not gotten a response yet. The photo next to it has been run through Grain Surgery using the program's default settings and then sharpened in PS7 using an unsharp mask with a threshold of 3, a 0.7 radius and a 90% sharpen setting.

The photo was at 72 PPI when I got it, so the question was how well does it work at a 300 PPI setting...
