In models inspired by non-commutative geometry, patterns of gauge symmetrybreaking are analyzed, and SU(5) models are found to naturally favor a vacuumpreserving SU(3) X SU(2) X U(1). A more realistic model is presented, and thepossibility of D-brane interpretation is discussed.Comment: 7 pages, 3 eps figures, requires PTP style files, minor correction
