No. printk hits console drivers why may or may not be frame buffer
interfaces. Has done for a very long time. Keith Packard has also been
doing stuff with crash time oops displays etc over an X display.

I would suggest we borrow the X idea and each VC is

	int display;	/* Display it is on (for console flipping) */
	struct something *vt;	/* VT which it is displaying */
	int x,y,w,h;	/* Window onto vt */
