This is great news.  I'll test it out tonight.

I was reading Peter Robinson's blog today[1] and he mentioned getting
AllWinner support, in Fedora 21.  Is that a realistic plan -- (from my
point of view) at least headless virt support for the Cubietruck in
F21?  I'm not too clear on how all these patches are going upstream,
if at all.
