I _think_ we just have just plain framebuffer drivers for the arm64
boards, no acceleration.

There is 3d via llvmpipe but not accelerated.

You will probably do better than 480p-like with a fast CPU, but
not at the same time as doing anything else CPU-intensive, and it
will use a lot more power than something with acceleration.

I was more specific with my wording than that, referring to gpio(4)
in particular ;) If you have such a device that attaches to ugen, you
may be able to access it via libusb userland programs.

(The USB GPIO modules are generally "some microcontroller with a
USB 'gadget' interface and GPIO, running firmware to interface between
the two sides" - there are similar devices where it's "a network
interface and GPIO, running firmware to interface between the two
sides" and those will usually be easier to work with from OpenBSD).
