Dual screen, XFree86
I had a hard time figuring out how to use two flatscreens with just one nvidia-card, but here is my sample XF86Config:

I really hope this little example of setting up a dual-headed (or dual screened) X11 for the DVI and CRT-outputs will help you. I didn't use Xinerama, and don't ask me how to clone the screen.If something is missing: here is my REAL XF86Config, it works, but its not that beautiful. (md5sum: a94f62e2a19d041d8efc2e5a06b6023e)
Single screen, Xorg
And for the ones with just one monitor and Xorg under OpenBSD, my xorg.conf is:
