As the others devs already mentioned, AC100 support in mainline is nearly complete. 
What is missing is the display support. AFAIK, this won't happen in the near furture 
(or NV or someone else steps up and pulls something out of his hat). Olof Johansson 
made quick and dirty port of the current driver to 3.2, but I failed to get it 
working here. This won't be useful for a stable series anyway. Remember the ~600 
pending patches?

As it looks now, we have to stick with 3.0 for 12.04. I hope this does not create 
problems. Chromeos normally follows the stable series (with a small time lag), so 
security patches and important bugfixes will also go into our kernel tree. But for 
this to work we would need to release our kernels independantly of the Ubuntu 
releases. Are all ARM machines (I mean the kernel) updated at once?
