Yes, it's a dump/restore of the existing root partition on the other
disk, and I can mount it correctly and verify this when booted off drive
zero.

Hmm. How can I verify this? The machine is remote and I've not got
access to the bios screen.

It will have to wait until a quiet period so I can reboot to verify, but
my memory tells me that when I tried to see what was on the disk from
the boot loader I got some message about inconsistent or corrupt
disklabel.
Is it possible that it's a bios issue and that the bios isn't correctly
configured for this disk? How might I work around that if that's the
case?
This is what fdisk reports:
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=3D238216 heads=3D16 sectors/track=3D63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=3D238216 heads=3D16 sectors/track=3D63 (1008 blks/cyl)

and this is the boot time probe:
