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.

Rich.
