I don't remember the format for fstab, but you can change the FS from RO to 
RW and back from the command line something like this:

mount -o remount,rw /dev/hda1 /mnt

mount -o remount,ro /dev/hda1 /mnt

(of course /dev/hda1 and /mnt must be replaced by the filesystem device and 
mount point, respectively...)
