nvidia driver problem [Was: new user question: debian on a Thinkpad T61]

I followed the instructions to install the nvidia drivers the Debian
way from this site:
http://wiki.debian.org/NvidiaGraphicsDrivers

Every command worked fine, with no error messages. However, when it
came time to reboot, I get a black screen shortly after the message
that says gdm is starting. After that, the system stops responding to
any form of input (no tty's either) and the only way I can do anything
is to force shutdown by holding down the powerbutton.

From my xorg log, it seems like everything is working normally, or at
least I can't make anything out of it. I've attached both the log and
xorg.conf.

Some possibly relevant system information:
This is a very fresh install of Debian etch 4.0 r2 (stable). The only
things that have been added since the system was installed are xfce4
along with a bunch of plugins, vim-full, and bash-doc.
Graphics card is Nvidia Quadro NVS 140M, which is listed on the
official Nvidia site as supported.

Any help would be greatly appreciated

Thanks!
