If there's no option to do what you want, a pretty simple script can do
it for you... quick example:

#!/bin/sh
PATH=/bin:/sbin:/usr/bin:/usr/sbin
cat /etc/fstab | while read line

do
        dev=`echo $line | awk '/by-id/{print $1}'`

        if [ -n "$dev" ]
        then real_dev=`ls -l $dev | awk -F/ '{print $NF}'`
                echo $line | sed -e 's|'$dev'|'/dev/$real_dev'|g'
        else
                echo $line
        fi
done

Only drawback to that is it screws up the whitespacing that was lined
up.  Side effect of the while read line bit.. works though.  Probably
more elegant ways to accomplish the same thing too.
