After quite a delay another kickstarter board has arrived, I got the H5 2G version.
There is a version of Armbian for it, so will check it out soon, but given the small numbers of production, and no apparent love for the H5's I doubt we'll see much in the way of graphics drivers for a while.
Ahhh no, I got that wrong, the Armbian is for H3, the H5 has no OS at all yet....well if you like writing OS's then that great...me...not so much, in the drawer of shame it goes for a few months.
