Why is xorg ignoring the frequencies I give it?

Miles,
Thanks for that but unfortunately those changes didn't help.
I'm running Breezy Badger 5.10.
I guess ubuntu just doesn't support my system. Should I report any of this
as a bug anywhere?
Looks like I'll have to put Mandrake back on my system. Shame.
Thanks,
Andy.

Hi Andy,
I notice your xorg log contains this:
> (EE) GARTInit: Unable to open /dev/agpgart (No such file or directory)
This part looks like an issue with your kernel. Is there agpgart support
for the i915 chipset? What kernel are you running? I am running
2.6.16-rc1 and dmesg says:
agpgart: Detected an Intel 855 Chipset.
agpgart: Detected 32636K stolen memory.
agpgart: AGP aperture is 128M @ 0xe8000000
This issue with agpgart support may be the reason you are getting this:
> (II) I810(0): 37608 kBytes additional video memory is required to
> enable tiling mode for DRI.
> (II) I810(0): 16100 kBytes additional video memory is required to
> enable DRI.
> (II) I810(0): Disabling DRI.
This is going to limit your 3D rendering / graphics accelleration, I think.
Since the SDM-S204 is a TFT screen with 1600x1200 pixel screen,
you might want to strip out the lower resolutions.
You might try the following changes to your config file:
Section "Device"
Identifier "Intel Corporation Intel Default Card"
Driver "i810"
BusID "PCI:0:2:0"
EndSection
Section "Monitor"
Identifier "SDM-S204"
Option "DPMS"
VertRefresh 57.0 - 85.0
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Intel Corporation Intel Default Card"
Monitor "SDM-S204"
# DefaultDepth 24
SubSection "Display"
Depth 16
Modes "1600x1200" "1280x1024"
EndSubSection
SubSection "Display"
Depth 24
Modes "1600x1200" "1280x1024"
EndSubSection
EndSection
I hope this helps a bit,
Miles
