xorg.conf - setting a specific resolution for monitor gets ignored (945GM)

[Dan Naughton]

I'm working on getting the dual head thing working, but dri won't work
if the virtual size is > 2048 - so I have make sure the combined
monitors don't exceed that  (At least I'm pretty sure that's the
approach).  I've been trying to fix the resolution of the monitor (I'm
starting with 800x600), but the xserver won't cooperate.

Section "Screen"
       Identifier "Screen0"
       Monitor "Monitor0"
       SubSection "Display"
               Depth    16
               Modes "myVGA"
       EndSubSection

Section "Monitor"
       Identifier "Monitor0"
       Modeline "myVGA" 38.22  800 832 912 1024  600 601 604 622
-HSync +Vsync

I got the Modeline from gtf
# gtf 800 600 60
# 800x600 @ 60.00 Hz (GTF) hsync: 37.32 kHz; pclk: 38.22 MHz
 Modeline "800x600_60.00"  38.22  800 832 912 1024  600 601 604 622
-HSync +Vsync

inside .gonf there is a preference for screen resolutions. the desktop
is either overriding what's in xorg.conf or the xsever is ignoring the
Modeline part because I'm doing it wrong.
