I haven't looked at the code yet but was wondering if there is any
provision for pre-probing devices.

specifically i'm interested in fixing the console stuff to be more
modular ie. allocating a device for input and another for output for
different subsystems specifically system console, DDB and GDB seperatly, 
it seems like after this new code i will have to start from scratch,
i'm just hoping there will be a way to do this and to notify a device
that it has already been probed or allocated for something else.

is this possible?
