You need a recent version of cabal i.e. >= 1.6.0.3. I don't think the haddock 
version matters much (cabal can handle haddock-1 and haddock-2, I think).

The problem is that haddock does not retain literate comments i.e. the .lhs 
preprocessor is run before haddock parses the file, and literate comments are 
stripped.

This has been fixed in cabal by having cabal preprocess the .lhs file itself, 
with a special preprocessor that retains literate comments. The resulting .hs 
file is passed to haddock, and voilĂ .

Before cabal solved the problem, I used to run a similar custom preprocessor 
over the Takusen source tree, and then invoke haddock manually to create the 
html docs.
