http://www.x.org/wiki/Projects/XRandR is a starting point, but
slightly out of date.
Here's the place where the latest formal spec lives:
http://cgit.freedesktop.org/xorg/proto/randrproto/tree/randrproto.txt

I think all the majors have some level of randr support, but what
version (1.2, 1.3 ..) varies, etc. Here's the Intel implementation,
that relies on all the new DRI/KMS Intel support.

http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/tree/src/drmmode_display.c

Thanks for diving in here.  Any progress or even conclusions on what
direction to head would be very helpful.

Best wishes,
