I have already tried setting the minimum refresh to 85, it simply forces me to a different mode. However, after doing further research, I found that the particular chipset I have DOES NOT support 1600x1200x24x85Hz; That mode is only supported at 60Hz, so it was really my misunderstanding.
I did find a handy site for calculating modelines though. http://www.hut.fi/Misc/Electronics/faq/vga2rgb/calc.html Thanks for your input.

You should have a subsection display with the depth and resolution you wish. Then you should set the default depth to that depth and remove / comment out any other subsection with the same depth if any are there. You can always try to trick your monitor by setting the minimum refresh to 85 (VertRefresh 85.0-160.0 # assuming it can take it) in the corresponding line. According to your XF86Config, you are NOT running VESA but the i810 driver. I don't know it well but I had one case when the accel driver only liked 16 or 32 depth but NOT 24. why don't you try 32?
