I think the most FPish solution would be this:

  newForeignPtr :: Ptr a -> IO (ForeignPtr a)
  addForeignPointerFinalizer :: ForeignPtr a -> FinalizerPtr a -> IO ()

That gives you an empty finalizers function and an add finalizers 
function, like [] and (:).

I don't really care, actually, as long as I can obtain the same 
functionality.
