Apparently they need the same treatment as primary planes. This fixes modesetting failures because of stuck cursors (!) on Thomas' i830M machine. I've figured while at it I'll also roll it out for the ivb 3 pipe version of this function. I didn't do this for i845/i865 since Bspec says the update mechanism works differently, and there's some additional rules about what can be updated in which order.
