Are ASA and ISO the same? Is digital really that much more scary than film?

How do we make Lightroom mimic as close as possible what the manufacturers do in that respect?
Or even more important, let’s first have a look at what they actually do when reducing noise. I don’t have in-depth knowledge of any of the camera manufacturer’s specifics or how Lightroom exactly does it, but based on what I’m seeing with my own eyes and based on my knowledge about noise reduction, the least I can do is try a sophisticated guess.
Why would you want to do such a thing? Simple. Let’s say you’re totally happy how Lightroom treats the pictures from your camera on all ISO levels up to 800, but starting from ISO 1600 you need that slight tad more noise reduction on all images. But just up there, all other images should be left alone. Or imagine you have two cameras, a DSLR and a point-and-shoot, and you import pictures from both cameras into Lightroom, but they both have very different noise characteristics, so you want to treat their respective images in a different way.
Has this ever happened to you? You have a photography workflow that actually works like a well-oiled machine. Shoot -> import/tag -> select/prune -> rate -> post process -> export. Lather rinse repeat. Wonderfully reduces the hassle of getting lost within those thousands and thousands of images. All from within one single application. Maybe two if you count an external image editor that gets involved every now and then, but then nicely hands the edited image back to Lightroom.
And then.. all of a sudden things “happen”, for example in the shape of new cameras and you realize that Lightroom has its shortcomings in one or two areas. Or is that so?
Let’s explore my little adventure involving Lightroom 2.2 and the new 5D Mark II.
