Some questions im surprised noone else asked yet

1. Are you getting the fbsd booloader selection  (F1, F2 and so on)?

2.  if you are, can you hit spacebar then type  boot -c to load the
module configuration screen before going into the full boot.  If you get
this far you need to select /deselect  drivers  appropriately for the
cards being swapped

3. once you've done that there are probably some  config  files  that
need hand editing, but Ive never used RAID just ordinary SCSI.
/etc/fstab should still look the same if it's still possible to keep the
drives as they are without any kind of reinstall, dont know about
anything, im just trying to throw up suggestions
Also dont know if you'll be able to get this far from a normal boot or
if you'll need the fixit floppy or something like that just to get into
files onthe hdd to edit them

hope this gets things moving a little
