In Distribution.Simple.Haddock, in the haddock function we have:

    withLib pkg_descr () $ \lib -> do
        let bi = libBuildInfo lib
            modules = PD.exposedModules lib ++ otherModules bi
        inFiles <- getLibSourceFiles lbi lib
        unless isVersion2 $ mockAll bi inFiles

So I guess the easiest thing to do right now is remove the "unless
isVersion2 $" . I'm testing this at the moment, so when I get it
working (or not) I'll let you know, and maybe send a patch.
