I have a dell 700m which uses the 855gm video card:
0000:00:02.1 Display controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02)
Xorg in dapper works OK for me, with two caveats: in order to get the widescreen to work, you have to use 915resolution, and in order to get dual head configs to work, you have to apply the patch I have pointed to in this bug: https://launchpad.net/distros/ubuntu/+source/xserver-xorg-driver-i810/+bug/26341
Have you tried using 915resolution? I noticed that you are setting the resolution to a widescreen resolution.
