I am running at 1600 x 1200 / 85Hz now.  Yea!

Here are the correct modelines for the GDM-500PS
   Modeline  "1600x1200" 220.00 1600 1616 1808 2080 1200 1204 1207 1244 +hsync +vsync
   Modeline  "1280x1024" 157.50 1280 1344 1504 1728 1024 1025 1028 1072 +hsync +vsync
   Modeline  "1152x864"  137.65 1152 1184 1312 1536 864 866 885 902 -hsync -vsync
   Modeline  "1024x768"  115.50 1024 1056 1248 1440 768 771 781 802 -hsync -vsync
   Modeline  "800x600"    69.65 800 864 928 1088 600 604 610 640 -hsync -vsync
   Modeline  "640x480"    45.80 640 672 768 864 480 488 494 530 -hsync -vsync

I didn't know you could type your horizontal and vertical freq ranges into
XFree86config, I thought you had to select one of the monitors provided.  Duh.

This is actually Synapse Engineering, I am at home right now.  My problem is overcome.
Thanks everyone!
