I'm sorry if I missed something obvious, but why don't you simply require the 
callback in the CAMLprim function's arguments and then wrap it in the ML code?

Something like:

.ml:

  type handler
  type callback = foo -> bar

  type t = handler * callback

  val foo : handler -> callback -> bar = "caml_lua_foo"

  let foo (h,c) = foo h c

.mli:

  type t

  val foo : t -> bar
