Since there's a slight chance your drive might change device nodes
(one boot it could be /dev/sdb, if you add or change something it
could end up being /dev/sdX) I recommend using LABEL based mounting. 
It's helpful (and easier) for using external drives.  It only works
with a couple of filesystem types, but ext3 is one of them

First, label your drive:
# tune2fs -L backups /dev/sdb1
(replace backups with what you like to label it as)

then in /etc/fstab instead of using the /dev/sdb1 use the label.
LABEL=backups    /backuppc ext3 rw,auto 0 0

The next problem is forcing it to be mounted before backuppc... if
it's not a script that will be replaced you can cheat and just put
mount -L backups
in the backuppc script before it starts.
