But they sell a card with Devuan pre-installed so it sounds like the answer is "yes".

I am hoping to use that for the purpose of learning more about devuan and gnu/linux as a whole.

Whenever I get it anyways...

Can you perhaps tell me if this will be feasible in the future?

Also, is it possible to remove the 4,9 kernel and install linux libre 4.1 in its place and remove 4.9 so that when it reboots, 
the 4.9 kernel doesn't cause any problems...

I was told 4.9 kernel + arm a20 do not mix well...

Any thoughts about this?

Edit: can devuan unstable run on 3.16? it seems linux libre 4.1 will be gone by the end of september...
