I have used a rubble trench foundation. The only detailed article regarding rubble trenches that I found was one in Fine Home Building, available in their concrete-foundations book. Otherwise they are mentioned briefly but without detail in numerous places. The article in FHB is all the information you really need. The most important aspect is making sure that the gravel is thoroughly compacted in shallow layers (6") and that the drainage tile is properly wrapped to prevent clogging.
Good luck
