Rich, all realists were presuppositionalists before the term became trendy. There are two ways to combat Kant's wall. Deny sense perception altogether, as idealists do; or insist that man's capacity to think is itself a rational category, as realists do. A rational capacity prior to the thought process is what we now call a presupposition. This is what Dabney was arguing for. Nash puts it is more modern terms that we would be familiar with.
