Well, I tried this and it did absolutely nothing.
The xorg.conf file can say anything it wants, but
the X server can have its own reasons for
deciding to ignore it :-).
Sometimes you can dig through the cryptic gibberish
in the /var/log/Xorg.0.log file and see why the
server rejects some modes. Possibly something
like adding vertical and horizontal refresh
info to the xorg.conf file will convince it that
it is OK to use a mode it rejected, possibly
you need to generate a mode line and cram
it down xorg's throat :-).
There is a program that comes with X these days
named "cvt" which can generate valid mode lines
that might work.
Some of my own experiences with different versions
of X can be found here (though the X server has
changed a lot, so not everything is relevant
any longer):

Okay, I made some adjustments and now the real culprit seems to be
showing its ugly head but I am not sure how to deal with it.
Here is the relevant lines from /xorg.conf/:
*Section "Monitor"
Identifier "Monitor0"
VendorName "Polaroid"
ModelName "FLM-2632"
Option "NoDDC"
HorizSync 31.5 - 50.0
VertRefresh 25.0 - 65.0
ModeLine "1366x768" 65.00 1366 1048 1184 1300 768 771 777 806 -hsync -vsync
EndSection
Section "Device"
Identifier "Videocard0"
Driver "sis"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1366x768" "1024x768" "800x600" "640x480"
EndSubSection
EndSection*
...and here is the response to it in the /Xorg.0.log/:
* (II) SIS(0): Not using mode "1366x768" (illegal horizontal timings)
*
Now, the funny part about it is that I can go into /xvidtune/ and
manually set it to the very same settings and the display goes into the
proper mode just fine (of course /Xorg/ resets it when you log out).
*This means that /Xorg/ is WRONG! *Now, how do I force /Xorg/ to accept
the proposed display setting?
