This isn't quite true.. Due to the implementation of console over
firewire, it will work before it is probed... This is due to the fact
that console over firewire examines the memory directly (becaue firewire
supports reading/writing memory w/o the host cpu's intervention), and
doesn't need anything special to be initalized...
Recently, loader was improved to support dcons, and support hand off
of the buffer from loader to kernel... I haven't tried this new and
improved loader, but it's suppose to work...
