nvidia cannot be enabled because xorg.conf md5sum doesn't match

The nvidia driver cannot be enabled in xorg.conf because xorg.conf fails the md5sum check. This is on a kubuntu dapper installed using the Live CD. I haven't touched xorg.conf manually and I still get this

If I run md5sum /etc/X11/xorg.conf | sudo tee /var/lib/x11/xorg.conf.md5sum

and then sudo nvidia-glx-config enable in a terminal it works.

I tried to modify packagelist-dapper.xml to add that command but I wasn't successful.

apt-get -o=dir::etc=/home/frank/easyubuntu/trunk/conf -o=dir::etc::sourcelist=sources.list --yes --allow-unauthenticated install nvidia-glx nvidia-kernel-common
