0033 There was a version of the nouveau DDX that relied on legacy
0034 ctx ioctls not erroring out. But that was back in time a long
0035 ways, so offer a way to disable it now. For uapi compat with
0036 old nouveau ddx this should be on by default, but modern distros
0037 should consider turning it off.
