As promised, here is my working X configuration for 2x2 monitors. The only slightly non-ideal part is that when an application is maximized, it spreads across 2 whole monitors (instead of just one, which happened to be the case when I only had two monitors working).

The SIGINT error that I was getting was from having two "UseInt10Module" options set. Should have looked more closely at the log files - I didn't think one was really being generated earlier. My bad!
