Thanks Marcel, your program does the business as far as memory goes. However BlackKnight? has another trick up its sleeve. It failes differently once the memory is reduced. Jonathon Hudsons Trapper extension seems to indicate it is attempting to execute an illegal instruction on the 68060. I am reasonably certain that I did run it through the C68 patch for the Qx0 but am now off to check that I actually did so. On QPC2 BlackKnight with the memory reduction all works.
