Put this in /boot/loader.conf:
nvidia-modeset_load="YES"
Remove nvidia related entries from /etc/rc.conf
You may need linux_load="YES" in loader as well if applicable.
Reboot after entries are made.

I have 
linux_load="YES" 

nvidia-modeset_load="YES"

in /boot/loader.conf
and I deleted the line kld_list="nvidia-modeset" from /etc/rc.conf, i.e. no nvidia specific settings are in /etc/rc.conf now. However, xorg still generates the error message "No devices found".
I have checked the information on such errors generated by xorg in /usr/local/share/doc/NVIDIA_ GLX-1.0/README  but I could not find anything.

You may be able to work around the issue by statically specifying the bus id of nvidia in xorg conf:
