I can see how my earlier response may have been come
across/interpreted as aggressive and/or demanding. Apologies anyone
got upset/annoyed.

Let me try in another light - if you guys are willing to have
xf86-video-rockchip or keep track of/co-maintain armsoc, pretty much
everyone will be over the moon. Personally I'd opt for the former,
taking the modesetting (the one in the xserver tree) as a base - it
has all the cool new bits ;-)
