Here are mine; I tried them all, and they always lock into 60Hz refresh. Mode: 101 (640x480) Mode: 112 (640x480) Mode: 103 (800x600) Mode: 115 (800x600) Mode: 105 (1024x768) Mode: 118 (1024x768) Mode: 179 (1280x768) Mode: 17b (1280x768) Mode: 107 (1280x1024) Mode: 11b (1280x1024) Mode: 120 (1600x1200) Mode: 122 (1600x1200) Mode: 124 (1600x1200) Mode: 199 (1920x1440) Mode: 19a (1920x1440) Mode: 19b (1920x1440) Mode: 22e (800x480) Mode: 230 (800x480) Mode: 108 (80x60) Mode: 102 (800x600) What about the VBE 3.0 arbitrary vertical refresh rate thing?
