Sorry for the delayed reply ... been crazy busy!

*Thanks so much ted ! you are really awesome!*

.. Yes i am trying to get these on both Android ( and run some kind of 
automation)  and an Arm Qemu for development.
I would be grateful if you can share the patches that  fix the issues 
that are known.... even if they are not fully functional ...

I can try to see if I can finish the automation part and send the 
patches assuming i can finish them before you do :)

Yes i will look into GCE as well.
