Linux – Xorg server won’t start after fresh install of Debian 5.04, screen goes blank (Intel Atom D510(Pinetrail) on Intel D510MO)

I have installed Debian 5.04 Lenny on my new Intel D510MO motheboard. I fixed some issues with incorrect drive mapping (for some reason during installation my hdd was on sdb, after a restart it is under sda – fixed in grub), and now I am struggling with getting graphical enviroment up and running, I installed the graphical enviroment using the Debian installer. I am not an linux expert by any means, I assume that I need to edit the xorg.conf file.

Any hints appreciated!

UPDATE1:

No change after dpkg-reconfigure xserver-xorg

Here is my current xorg.conf:

# xorg.conf (X.Org 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*

#   sudo dpkg-reconfigure -phigh xserver-xorg

UPDATE2:

I have installed vnc4server package. I can connect over vnc from my windows 7 laptop and i see empty desktop with terminal window open. Seems that the xserver and gdm are running but they cant talk with my GPU. I am not sure if a can use any gui tool to configure it overthe vnc, as all I see is the terminal window, no taskbars etc.
