Paul, Thanks for the tip on the pseudoloaders! As it turned out, my assumption about the malfunctioning depth partition had nothing to do with the "actual" size of the model. It was correctly accounting for my matrix scale after all. Someone else on the list pointed to a minor tweak to some tolerance values that did the trick.
