there is way out.
you can label all your filesystems and specify the label instead of the device file in fstab.
for example to label '/' :
1. boot fbsd into single-user mode
2. tunefs -L root /
3. change the first field in the fstab entry to /dev/ufs/root
4. if you are running fbsd 6.x add: geom_label_load="YES" to /boot/loader.conf
do the same for all the other fiesystems.
