using what I must assume was the same installer/exploit game saves.
From the way you've described your Xboxes I suspect that's not a correct assumption.
I'd be very worried about the SID 3.1 Xbox as well, simply because SID 3.1 has no shadow C and is very old.

Clearly something isn't the same and I'm trying to work out what and whether it matters. Whether the Backups are messed is my greatest concern for the very reason you said: because it's not using a shadow C. They're my get out of gaol if something does go wrong, unlikely though I think that is.
Backups provide absolutely no protection against overwriting your softmod if you don't have a shadow C - the only real protection is updating to a softmod with Shadow C. Also, FYI, there's nothing on the backups that you can't extract from CASH, Slayers or AID and recreate in a few minutes.
The only backup you need from your Xbox is the eeprom, which is unique to each Xbox, and which you should backup properly i.e. somewhere other than your Xbox.
