Hi Gilles,

We already talked about the vexpress, it was at the beginning of the 
rtcan discussion.
It used to work (and pretty well), my configuration was:

linux-3.2.21+ipipe-core-3.2.21-arm-1.patch

and I have just successfully tested

linux-3.2.21+ipipe-core-3.2.21-arm-4.patch
as well.

There is likely not much missing for having it working on the 3.5.7 
kernel. I am taking a look.

Cheers
Thierry
