There's a patch series for this and pointer barriers (which Unity might
want to use, too, for the BDB + multihead) on the xorg-devel mailing
list.  The crtc-clamping works and if we really wanted it the patch is
relatively safe and could be FFe'd.  The pointer-barriers need protocol
changes, and I'd be hesitant to include them before the protocol has
been finalised.
