Additionally OpenGL applications that were running triggered a number of error messages from the NVIDIA driver. This occurred because the vt efifb back-end did not signal the X server to release the display before suspending (or to re-acquire it after resuming). The NVIDIA driver includes code for smoothly shutting down and re-initializing the GPU, which was not getting called. Since the NVIDIA driver doesn't currently support framebuffer devices and vt is forced to fall back to the efifb back-end, add vd_suspend and vd_resume members to connect the suspend/resume path. This ensures the X server is properly able to re-initialize the display.
