The tl;dr is that Linaro's upcoming dmabuf solution for Unified Memory will enable the sharing of GPU objects across memory buffers and that Dave Airlie's X redesign will permit loading drivers without loading screens.

This work isn't expected to come together until at least the middle of next year. Aaron Plattner of Nvidia has expressed interest in some sort of binary support for Optimus for X once the work is in place yet this may come into conflict with his/Nvidia's anti-Wayland stance right in the middle of the transition to it.
