Building the image was surprisingly simple and my first impression is that it works just fine. Thank you all so much!
 
I uploaded the image Armbian_5.74_Bananapim2ultra_Debian_stretch_dev_4.20.6 here, in case anyone would need it: http://www.share-online.biz/dl/YQ026FMP1LO (I hope this link is allowed; sorry, if not).

nope.. it's csc only.. means no 'official support'
 
 

You can, but not in this section, but here: https://forum.armbian.com/forum/23-community-forums BTW. board boots, just HDMI is broken - fixed in 4.20.y+

Wifi is also ok in 4.20.y DEV branch.

@Mario Schmidt Dont give up
The actual 4.20.6 image for the M2 Ultra does boot fine on the M2 Berry and HDMI/WiFi is working (tested console-server).
But it isnt directly downloadable at this time - you have to compile the image with the armbian-build-system:
https://docs.armbian.com/Developer-Guide_Build-Preparation/
 
A  small virtual (or real) Ubuntu-18.04-x64-Mini-Server and some commands and you are up and running for compiling the DEV-image with 4.20.6
