You've probably already tried this, but how about:
mount -o remount,rw /

as root user at a console after boot?  At the very least it should let
you start changing fstab.  The only time I've seen this not work is
when there are HD errors and somewhere along the way the hardware
refuses to allow writes even after the directive above.
