Doing some quick digging the answer is we should be able to support it.
 W1 (one wire) has a gpio driver, which should work on the MinnowBoard
MAX.  It won't exactly work out of the box, as it has the same problem
that spidev has, in that we don't have quite the same system descriptors
as the Pi.  That being said a board file or a dsdt shouldn't be hard to
add, and I'll see if I can find a sensors to pick up so we can add
support into the extras repo for W1 on the MAX (from a software
perspective).
