That's not really the same thing, if I'm understanding the original question correctly.  I think the main points of such a cheat sheet would be that it is (a) organized *logically* (as opposed to zvon which is organized alphabetically) and (b) able to be easily (and beautifully) printed out.  It's the kind of thing you would keep on your desk, right next to the keyboard, and you'd flip through it now and then when you have questions like, "now, what was the name of that function again?  some? init? take? I forget."  or, "which Arrow combinator do I want, (***) or (&&&)?  I always get them confused."  It could also include things like some of Cale's fold diagrams, funny quotes from #haskell, and so on. =)

Anyway, I think it's a great idea.  Maybe tomorrow I will start a wiki page to organize/discuss what information should be on such a "Haskell cheat sheet".  No one's ever made one as far as I know.
