Just to add an engineering complication to this, it is also true that re-radiation of that heat to the air must happen, or the brakes will fail. This radiation of heat will be proportional to the total surface area of the rotor, and that can be increased (or decreased) with drilled holes. Lots of little holes will do this best, but location to avoid any heat transfer restriction is also important. I think the bottom line would be how well the rotor is engineered, and not simply whether they are cross-drilled or not.
