2nd question on OF_DYNAMIC in a week... I haven't really looked at it. I
would suggest looking at the existing users (only powerpc iseries and
pseries). My concern using would be that the reference counting is not
correct for many drivers as of_node_get/put is a nop without OF_DYNAMIC.
You can also activate/deactivate nodes with the status property.
