Also, sometime ago someone suggested that you can grab the kernel AMDGPU package from the proprietary driver and use it with the opensource driver, doing so will allow Vega to display video from its connectors. This really works? Somebody tested it? Can I use this it with a RX 470?

Last time I saw something like that, back in Ivy Bridge days, it required chipset support, but it was on windows, and used a sketchy proprietary application "Lucid Virtu MVP". And by now the idea got dumped.
We look at Lucid Virtu MVP; a big technology for the upcoming Ivy Bridge platform due later this month. Is it any good, though?
By looking at Arch wiki it seems that in modern laptops it's all done software side though (I don't know what "plugged into a framebuffer" means, if this is software side or there is a dedicated hardware communication channel for that). https://wiki.archlinux.org/index.php/Hybrid_graphics

So I shut the PC off, changed the video cable to the motherboard, unplugged the power cord of the card (otherwise I cannot enter the BIOS), changed the primary video output to onboard on the BIOS, shut off, plug the power cord in the card, started and tested it.
It only worked for glxinfo and glxgears. All the other applications, like Firefox, Steam, Unigine and Unreal demos, refused to work.

It should be simple enough, but didn't work.

It's some kind of SLI/Crossfire which works with any combination of GPU, so you even do NVIDIA + AMD + Intel GPU or something like that AFAIU.
Does Vulkan support that as well?
