    Hi hoskit, yes I was able to get the job done. I suggest you to take the very latest development armbian nightly which already has the HDMI bits in the device tree, just not to tinker about the kernel compilation and other messy things.
    The guy (mripard) on github fixed some regression he introduced that broke the mali kernel driver compilation on slightly older kernel, so now compilation and installation should be pretty accessible.
    I tried only the framebuffer version, and yes, it was working pretty well: I tried different OpenGLES2 demos from the official Mali SDK and they all worked without issues

    Image Yocto with kernel 4.12 (for S905X).  (v20170825)
    To download the image. Unzip. To record on the SD card. Rename the /boot partition file of the dtb to the "dtb.img". To download the script s905_autoscript. Add on the SD card in the /boot partition. On TV Boxing should be informed (with other images) is activated multiboot. Connect the SD card to TV box. To turn the power on. After running the screen is in hibernation (from your watch) for desktop display you have to press a key on the keyboard or moving the mouse.

    USB works in the kernel 4.12.9 (kernel source Neil Armstrong).

    None of those voltages are fine with the boards. The board may run, but USB devices and HDMI devices won't work as long as they receive the proper voltage directly from the source.
    Also cheap power supplies with selectable output voltage usually have very little output amperage (200mA if you're lucky. These boards require 2000mA to work reliably with some USB devices attached)

    You may take a look to this thread too:

    I tried to run the Opi One at 1.2 Ghz with 1.100 volts. In my experience, it works flawlessy and I tried all the stress tests suggested by tkaiser with success, plus I stressed it with cpuburn-a7 for some hours (with huge heatsink!!) without problems.
