I did a quick experiment and it looks newbusification will solve the
problem. Of course this opens pandora's box. The whole frame buffer
code is unsuitable of being newbusified. By design, I might add. It'll
be a lot of work. I think a kluge is called for but I'm not entirely
sure it's something I want or should spend my time on. I need to give
it some thought...
