The display on my Q8H is a bit off to the left. With the simplefb
bindings from your kernel sunxi-wip branch, I get a nice console.
Though I've no way to type, at least I can tell my tablet is on. :)

Could you briefly explain how to convert the values in the fex
file to the mode line here? It could also help others with
enabling display on their tablets.

Thanks
