Bug Description
Binary package hint: kdebase-workspace
System works fine in Hardy. Intel D945Gnt with Intel integrated graphics. Hitachi CM721F monitor gets display out of range error no matter what resolution or frequency I try. Tried dpkg-reconfigure on X. Tried xfix in the recovery console. System works fine with a Viewsonic VA903b LCD.

[Problem]
Intel D945Gnt + Hitachi CM721F monitor gets display out of range error on xserver 1.5.2.
[Discussion]
From the Xorg.0.log it appears confused what resolution to use, and ends up picking one the monitor can't do:
(II) intel(0): Using fuzzy aspect match for initial modes
(II) intel(0): Output VGA using initial mode 2048x1536
From the EDID it appears this monitor provides one modeline:
Mode "1600x1200" # vfreq 75.000Hz, hfreq 93.750kHz
DotClock 202.500000
HTimings 1600 1664 1856 2160
VTimings 1200 1201 1204 1250
Flags "+HSync" "+VSync"
EndMode
I'm assuming that it ought to be matching this modeline:
(II) intel(0): Modeline "1600x1200"x75.0 205.99 1600 1720 1896 2192 1200 1201 1204 1253 -hsync +vsync (94.0 kHz)
So why might it not be matching up properly? Where is the 2048x1536 resolution coming from? Is that what it's actually trying to use? Is there a way (e.g. a quirk) to force it to not use anything above 1600x1200?
