There was a proposal a long ways back to allow X to download instructions to the kernel on how to restore the video mode. The proposal was to code the instructions as a forth program that frobbed registers appropriately. The kernel would have a small forth interpretor to run it. Then switching resolutions could happen safely in the kernel.
