so here is where i am so far...
i installed the kernel header 2.6.10-5-386
installed the drivers successfully
edited the sudo nano /etc/X11/xorg.conf EXACTLY like in your walkthrough
saved&exited
tried to restart gdm and got "I cannot start X server. It is likely not set up correctly" and asked if i wanted to view the log.
then i rebooted and the same thing happened.
