Slightly unrelated, but what is the state of this driver? I believe
"modern" drivers are supposed to register as a kernel modesetting
driver to the drivers/gpu/drm framwork rather than the traditional

You have done a great job on cleaning it up and I'd love to see this
all working again in 3.7, even if we have to adapt the bindings
