I use a Compaq at work with Intel 845 (or something like) and under Windows
you can have 1152x864 but X claims the card doesn't support it !! So assuming
the XF86Config file is correct then maybe X simply does not support that
resolution on that card. Anyway XF86Config (the Red Hat and Mandrake one is
in /etc/X11) should have something like the following in it (probably better
to use whatever X configuration utility comes with your distribution):
Section "Monitor"
Identifier "monitor1"
VendorName "Generic"
ModelName "1280x1024 @ 74 Hz"
HorizSync 31.5-79.0

# work with if the auto mode selection does not work
