I will probably get a Khadas Vim sponsored by the LE team / Chewitt which is based on a S905X but if you have a S905 box to spare I wouldn't complain to get one. In theorie if it works on the KVIm device it should work on others too but of course it's easier to create a working build if I can debug it myself.
Basically S905 devices are now supported by Le 9.0 and I already build a S905X image for KVIM which has all the features of my RPi build. If you have some specific patches feel free to post them here.
