Known Issues:
* Composite video out does not work
Selecting composite video out (see README) causes the system to hang
on boot. Investigation of this is pending.
Thanks to Hans for his work on this, this allows me to use the
Cubieboard instead of the Raspi and that feel far more sane :-)
However I have 2 board running now and both exhibit the same problem, a
constant extra load of 1 which i guess is due to some process stuck on
I/O but i can't identify the issue:

This is up2date Fedora 18, with Hans experimental kernel (note a yum
update "upgrades" the kernel and the Cubies won't boot again, one need
to reinstall kernel and associated modules).
I was initially thinking it was due to the microSD card bad quality, but I
tried with 3 different cards and always got the issue, so that's
something else.
Machine are basically on runlevel 3, ethernet, no active USB device,
video unplugged, I'm a bit puzzled.
How do I find out the stuck process leading to this extra load ?
