Stuff that is mentioned in /etc/fstab and not having the "noauto" option mentioned usually gets mounted at boot time by something running 'mount -a', but I'm not absolutely certain if that's the case on the empeg too.

The rw(m) and ro(m) programs are just shell scripts. You could modify either pair to include the new partition or create a third pair specially for the new partition.
The content of the existing ones should be a good start.

Oh, don't forget to incorporate, if you haven't already, the speedup fix mlord posted quite a while ago.
