compiling works fine as SPJ pointed out.

There's little overhead because of the additional hs-boot files. Do you 
only have cycles involving 2 modules? If your modules are small enough 
(below 300 lines) I would try to avoid the recursion. I had problems 
running haddock over recursive modules. (no idea about cabal)

No, but your ghc-options list is not Haskell-98, too. Maybe you want to 
give hugs a chance?
