I'm not sure if this information will be helpful (caveat user), but I 
have a Sony GDM-F500, and this little exchange of email spurred me to 
figure out what it runs like in 1600x1200 resolution.  (Usually I run 
at 1280x1024.)

My display card is a Matrox Millenium G400 16MB.  I ran XF86Setup, then
on the appropriate screen, I input the horizontal and vertical
frequencies from the monitor specifications (30-121 kHz horizontal,
48-160 Hz vertical).  The end result is that I'm now staring at a
1600x1200 screen with an 86 Hz vertical refresh frequency.  Looks like
it can also do 1280x1024 at 100 Hz.

I don't think you'll be able to use my modelines verbatim, but here they
are anyways:

   Modeline  "1600x1200" 220.00 1600 1616 1808 2080 1200 1204 1207 1244 +hsync +vsync
   Modeline  "1280x1024" 181.75 1280 1312 1440 1696 1024 1031 1046 1072 -hsync -vsync

Hope this helps...

Bruce.
