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 ?
