I don't exactly have that number but I believe you can go under 100ms.
If you have a look at my presentation at ELCE [1] or that video on
youtube [2], we basically are able too boot an start an openGL
application under 600ms from reset.

But that is a lot of self advertising, we can continue to discuss that
off the ML if you want.
