Wandboard Dual and Crochet-FreeBSD

[Scott Ellis]

I submitted a bug and I am volunteering to test. 

I only have Quads and Duals.

Could I ask that you submit a bug here?

I only have a Quad, so that is what I built for.  I am willing to make some
fixes, if a tester will volunteer to verify them on the dual.
