Almost. people tend to not fully comprehend that, these days, most X.org
drivers consist of at least two components: a kernel module and an X.org
driver (and you can add a Mesa DRI library to that, for many that
support 3D).

What's happening here is the nouveau kernel driver is getting
automatically loaded, and that's stopping the nv X.org driver from
loading. Probably all we can do about this is have system-config-display
block the nouveau kernel module from loading if you configure nv as the
X.org driver; I'll file a bug for that. To do it manually, just add this
line to a file in /etc/modprobe.d/ (you can call the file anything you
like, as long as it ends in .conf - for
e.g. /etc/modprobe.d/no_nouveau.conf ):

blacklist nouveau

then either reboot, or just run 'rmmod nouveau' as root and restart X.

Have you filed a bug on the fact that nouveau does not work with your
chipset? If not, could you do so, and include the /var/log/Xorg.0.log
and dmesg logs? (If you have, what's the URL?) Thanks!
