It's more complicated than that- the driver has to support the new KMS driver architecture, where the kernel is in charge of setting up the display and doing draw operations, which the X server used to handle. (Which was why before, you could only have 1 instance of X11 and OpenGL, and switching between virtual terminals took so long) So Wayland won't run on nVidia's (fast) drivers, because they still use the old model where X was in charge of the graphics card.
