In the absence of MALI support, there are
* Supported USB display adapters (
http://man.openbsd.org/OpenBSD-current/man4/wsudl.4 +
http://man.openbsd.org/udl.4 ),
* miniPCIe-based video adapters (
http://versalogic.com/Products/PDF/DS-MPEe-V5.pdf , not sure if that
chipset is supported), and
* miniPCIe to PCIe adapters (
http://www.banggood.com/Mini-PCI-E-Version-V8_0-EXP-GDC-Beast-Laptop-External-Independent-Video-Card-Dock-p-1011222.html
) that you can plug an ordinary graphics card to.
iMX6 (supported) and RK3399 (not supported) have miniPCIe.
Not sure if iMX6' (mini)PCIe is supported on OpenBSD?
I guess otherwise the ARM architecture not brings any constraints in the
ability to use these.

Juan,
Ok you're right this is unimportant. Just for completeness for now,
Is it possible to do an altogether opensource unaccellerated graphics
driver for MALI today, based on all sources you've seen out there?
Also what's KMS about, I see https://lwn.net/Articles/568169/ and
http://events.linuxfoundation.org/sites/events/files/slides/brezillon-drm-kms.pdf
but don't make too much sense, what's it about?
Anyhow yeah you're right there's much more important things like
64bit.

Juan,
Re console:
Is there not even console graphics on the ARM boards yet, so only
serial
interface?
The HDMI/Video port requires a KMS driver.
Re X:
Using open-source drivers only, you can actually run X on the Mali
GPU:s
(i.e. the chips in most ARM:s), unaccelerated.
IIRC, the most of ARM boards on Linux use a KMS driver + Xorg
modesetting driver. Anyway, the devs are working on more important
things for the platform.
Here's a video showing this on an EOMA68-A20 board in some Linux:
https://youtu.be/iM4cDjGY9vY?t=180 .
The low speed of the A20 CPU results in some flickering when
switching
windows and tabs. I think on the modern ~2Ghz ARM:s e.g. RK3399, as
its
single-thread and memory speed is approx 5x that of the A20, the
unaccelerated X should provide a perfect desktop experience (web
browsing,
openoffice etc., anything except video decoding).
It would be super ultra cool to be able to do this on OpenBSD some
day.
