X.Org on NetBSD: the state of things

The big question - does all this have a future? The good news is that all new hardware has generic support in X. Someone writes either a modesetting kernel driver or a classical wsdisplay kernel driver and they will be automatically supported by the associated drivers in X. The bad news is that to have applications running we require access to a larger open source ecosystem, and that ecosystem has a lot of churn and is easily distracted by shiny new squirrels. The process of upstreaming stuff to X.Org is an ongoing process, but it's likely we'll run into things that will never be suitable for upstream.

I had no idea NetBSD did such heavy customisations of its X.Org implementation, many of which have never made their way upstream. The project also maintains support for several older GPUs, uses its own input driver, and more - it's quite impressive.
