Success: tested RV2 with GPU on Armbian-noble-nightly. It's a bit hacky but should work. I created a mirror of the relevant packages from Spacmit/Bianbu. Only packages with source, specific to k1x / video / gpu plus chromium. Mirror project is here, in case you want to mirror yourself or miss a package: https://codeberg.org/sven-ola/spacemit-mirror
 
After getting up Armbian-noble-xfce4-nightly on your Spacemit/K1 board (that includes Ky X1)
Add mirror repo to /etc/apt/sources.list.d/sven-ola.sources (Note: this is experimental) Types: deb deb-src URIs: https://privat-in.de/armbian Suites: noble Components: main Signed-By: /etc/apt/trusted.gpg.d/sven-ola.gpg  
Get my repo key with  wget -O /etc/apt/trusted.gpg.d/sven-ola.gpg https://privat-in.de/armbian/key.gpg Give the mirror some weight, add an /etc/apt/preferences.d/sven-ola file Package: * Pin: release o=Sven-Ola Pin-Priority: 1000  
Install GPU support  apt-get update apt-get install img-gpu-powervr apt-get dist-upgrade Note: this will downgrade mesa-25.x to mesa-24.x from Bianbu/Spacemit
Install a Wayland-enabled GUI (tested: gnome) apt-get install gnome-core systemctl disable lightdm If asked, select gdm from gnome instead of lightdm from xfce4.
After rebooting, click on your user, then stop and select Gnome with the lower right gearwheel icon.
I also installed glmark2-es2-wayland to check if that runs. It shows 417@800x600 which is faster than software mesa...
