All CAM device instances 'exist' before the boot up is allowed to progress.
If you attempt to open the device while it is initializing, you will block
in open until the initialization is complete, but the open will eventually
succeed (assuming we were successful in our attempts to initialize the device).
The same probing mechanism (parallel probing) is used to find our root
device, and I have not heard of an instance where that has failed. I would
not expect sysintall to see the world any differently than the mount root
code.

Perhaps there is another bug in the ahb driver...
