I am not sure.  It might have, but there might be more breakage
accumulated.  My current opinion is that both vbox and nvidia (as well as
in-tree and out of tree drm modules) must be marked as tied.  The modules
definitely depends on much more kernel interfaces than a typical HBA or
network controller driver, for which the stability claim is actually
intended to apply.
