97%+ probability you only need an adjustment or two or three in
/etc/X11/xorg.conf. Intel is often a problem to get set up initially, for
various reasons, but generally works fine once configured. I have Etch and
Kubuntu and more running on i815 video, and Kubuntu, Mandriva & OpenSUSE on
i845G.

HorizSync looks suspiciously low to me, so I suspect you might be able to get
1024x768 by merely changing

	HorizSync	28-49
to
	HorizSync	28-75


If that fails to get the job done, try switching in Section "Device" from

	Driver "i810"
to
	Driver "intel"


If that fails, try adding to Section "Device":

	Option "NoDDC"


If it doesn't help, remove it, and check for a motherboard BIOS upgrade.


If none of the above works, try grafting in the complete sections of the
following from xorg.conf from a Lenny boot:

Section "Device"
Section "Monitor"
Section "Screen"

>From Section "Screen" you can safely omit all subsections except those for
the DefaultDepth. Nothing in Section "Files" is relevant either, so that can
be left out if you need to paste again.

If you have any personal web space, better to put there and just include a
link in the email.

Don't forget to back up xorg.conf before changing it.
