I finally grabbed an xorg.conf from the computer that has the 865G. I 
run 1280x1024 at 75HZ. You can see if the attached file helps out any 
for your system. I have a different monitor than you listed in the 
xorg.conf, but the monitor I use is a newer one and even LCD. It works, 
so I left it as is. You might check your specs for your monitor and 
adjust accordingly.

It did a horrible job.:-)

There are settings that deal with legacy video which should be set to 
8MB. The default is 1MB. If the setting for legacy (VESA, I believe) is 
not set to 1MB. One of the now moved on Kernel developers pointed out 
this setting. The name might be described in other terms. It relates to 
video memory anyway.

There should also be a setting for shared video memory. I use 128MB but 
you can select lower or higher according to your desires. This name 
could vary also.

It is pretty messed up when reviewing the settings.

You could manually restrain the range with 60-60 or 50-70 and similar 
concepts.

I hate to say this. I will anyway.
With your posted s-c-display generated file, 640x480 is no surprise. :-)

I hope some of this response helps out. I guess filing a bug report and 
attaching your posted xorg.conf file against s-c-display would help the 
developer realize a worse case scenario.
