As I recall, it died because the whole notion was very poorly defined
to begin with.  The idea was to stop waiting when all the SCSI buses
had been scanned -- but there's no way to know when that occurs because
new buses can be added at any time.

Maybe a better approach would be to poll at reasonable intervals 
(HZ/10, for example) for the existence of the root device.  If it 
hasn't appeared after some reasonable time (30 seconds?) then give up.
