As far as I understood CRTC 0 is disabled, because it is only capable of generating analog video signals. I'm using a HDMI monitor, which is controlled by CRTC 1. To use multihead (not clone), you have to connect a analog (VGA) and digital monitor (in my case). Each monitor will use one CRTC and each CRTC will show a different part of the same screen. With this in mind every active CRTC should be listed as "native Windows monitor".
Mostly for reference, what driver are you using? Have you explicitly configured a primary display at all (either through the xorg.conf "Primary" option for the monitor, or with the xrandr utility), or is it just picking up the first display connector and incorrectly assuming it's connected?
