I can only answer partially... I can change the id to allow to have both the hd connected only in 10/12 hours, so no fx until then.

The script I used is betxen's , and the prom settings are correct ( the old hd boots once reconnected )

What is the script?  The best online resource I can suggest is Ian Mapleson's page on cloning, at http://www.sgidepot.co.uk/disksfiles.html#CLONE (use the tar method if the disk is EFS rather than XFS).  I do this quite often without any issue, mostly on Indys, though I use tar slightly differently (to exclude /proc and mounts).

If you boot with the original working disk, with the clone connected, what does fx(1M) show for the clone?
[start fx (you need to be root), select the controller, drive,and LUN 0, then do label, show, all]

and what does the output of nvram(1M) show, especially for SystemPartition and OSLoadPartition?
