making haddock docs with inter-package links?

I have a bunch of libraries I'd like to re-release (via hackage & darcs) with haddock 2.0 docs. Each package has doc links within the package, to ghc libs, other packages on cabal, and to some packages with haddock docs in other places (wxhaskell, in particular). Is there any way for me to get all of these links working? And if not, is there a solution in the works? Thanks, - Conal
