Accelerated X probably got the databooks for the chips under NDA from intel. Several xfree86 developers probably have the databooks as well, they are just not publically available.
many laptops default to one crtc driving both outputs, but this is not necessarily always the case, as evidenced by your laptop. you may want to look in the bios there may be a way to set the default crtc configuration. I'd expect you may see fewer and fewer laptops with this behavior since it is safer to use one crtc per head. that way you won't accidently drive an external monitor with a signal that may damage it. I suspect that they only way to drive "clone" mode on your laptop is to use both crtcs. once you have that working adding dualhead support is trival since all you have to do is point the crtcs at different parts of the framebuffer.
