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

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 */
