What about vt_upgrade()? It's called later in the boot process:
/* Delay until all devices attached, to not waste time. */
SYSINIT(vt_early_cons, SI_SUB_INT_CONFIG_HOOKS, SI_ORDER_ANY, vt_upgrade,
&vt_consdev);
However, it's called from vt_allocate() too, so you would need a flag in
struct vd_device->vd_flags to record the fact the handlers are registered.
The core handlers would then call backend-specific handlers, if the
backend provides them.
