Repost: Drive jumpers - was: Boot Timeout?

I currently have a HDD as the primary master, a CDROM as the secondary
master and a HDD as the secondary slave on my FBSD box.

FBSD detects them as ad0, acd0 and ad3, respectively.

If I change the drive jumpers to make the HDD the secondary master and
the CDROM the secondary slave, is it correct to assume that FBSD will
detect them as ad1 and acd0?

This configuration will break /etc/fstab, as well as anything else that
references the HDD on the secondary IDE channel. Other than /etc/fstab
and personal files, what should I edit to reflect the hardware changes?
