Right, I'd forgotten why I set that by the time I'd finished the patch.
I'm interested in learning about bus* in any case, so if nobody more
clueful takes this forward within the next few months I may come up with
something, but obviously rather slowly.

Yes, that would be fantastic. As explained, the patch fulfilled my aim
of being able to run Cube on NetBSD and I wondered if anyone else may be
interested in that, but it's far from being complete and it would be
great for someone even semi-competent to take this on and bring NetBSD
up with FreeBSD/Linux for DRI. Nice little project for someone with
more spare time and skill than me :-)
