How to change xorg.conf to use intel driver

I've been trying to get the intel driver to work correctly with my
Intel 915GM/Dell 2007WFP under Debian "lenny", but can't seem to get
any traction.
Previously, I'd had the i810 and 915resolution hack working nicely
with Debian "etch", but I upgraded to "lenny" and neither the intel
driver or the i810 seems to work for me.
I have xserver-xorg-video-intel 2.2.1 installed and get the following
outputs from xrandr and ddcprobe (run while using vesa driver,
installed as fallback)
#xrandr --verbose

I want to use the 1680 x 1050 resolution, but Debian's configuration
tool let's me down (screen displays black when I log in via gdm) and
I've had no luck with a variety of xorg.conf changes.
I'll throw out one xorg.conf I tried and hope someone can steer me the
right way:
# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

gdm displays the login screen fine, but when I log in, all I see is
black. Generally, I've been logging in over ssh from another machine
and restarting X after modifying xorg.conf.

I'm guessing the intel driver is not detecting my monitor correctly
from the log output, but I am not sure of this.
I've attached the entire Xorg.0.log to this email, if it is of more help.
I know there are newer drivers... if someone knows that they will fix
my problem, please point me in a good direction for either installing
a newer driver (not currently in "lenny") or building the newer ones.
TIA
