Possibly, it depends on the console/input developers if they want to add something like fb_flash_logo() besides doing a kd_mksound(). Also, if you don't mind compiling in a bunch of logo images to your kernel.
On a more practical note, the "scissors test" (I should have named this "exclusive clipping test") can perhaps be enabled arbitrarily by userland clients. You'll be left with a rectangular screen space that will not be touched by the console. Then a distributor can do whatever it wants with that screen estate, say an animating splash or a pop-up window, which in theory can be triggered any time.
