If you have MB Look Suite, pull up a preset and note the settings for each parameter. You should be able to recreate the effects in Photoshop. You may have to have a gamma adjustment twice, once to start and once at the end. It is these kind of manipulations that give MB its unique looks, so don't simplify the look with a single gamma adjustment, for instance.
From AutoFX, I have Mystical Lighting, Mystical Tint and Tone, and the DreamSuites. All are very cool. I suggest you go throught the website and click on all the examples and take a look at all it can do. There are some tools that will allow you to change the lighting of a scene altogether. Scratch that.... lighting of a PHOTO. I imagine it would be harder to do the whole scene.
The page I linked to is a list of all the filters in the product. Click on each to find examples. I think the "Old Photo: Color" filter could get a good bleach bypass look with a little tweaking of the settings.
There's been a bit of an over simplification with some of the responses.
Some of the looks are NOT a matter of single/double gamma tweak or Curves settings. Isolating highlights, mids, and shadows, using multiple instances of each with differing effects/adjustments in coordination with blending modes is the way to get many of the looks he mentioned.
Alien Skin software has a pretty good suite called "exposure" that emulates filmic looks for stills. Sure, you can do a lot of it without the plugin, but the plugin is still quite good.
