Actually, xf86CrtcConfigInit() would be the natural choice, but that
returns void unfortunately.

Actually, no driver change is necessary at first, only if some driver
wants to remain backward compatible. Heck, I don't even know whether we
want to do that with radeonhd, but I want to be able to if I wish.

Please check the attached patch, it should do the trick. I'll commit if
you agree that this is fine. My buildsystem is currently not in a state
to build master, but that'll hopefully change over night so I can build
verify tomorrow. :-/

I said run-time check. You're talking about a compile time check, for
that the macro RANDR_13_INTERFACE is sufficient.
