Care to explain a bit more why you need to initialize those devices
early on?

Usually moving things earlier and earlier is an endless loop 
adding more and more nasty dependencies..

I'd rather see things getting initialized later as regular
device drivers so we have decent kernel error messages when
something goes wrong without having to enable debug_ll.

Tony
