The chart attachment was lost and thus not visible. I would agree the the "DME required" statement is over-riding. After the FAF are there DME v ALT values given? If so that just re-enforces the fact of needing a DME.
I have seen other charts which e.g. say NDB ILS. The only reason I can find for the NDB is that the procedure starts outbound from the NDB. However, within ILS protection criteria it would be possible to establish straight-in for ILS at or above MSA, no radar. It's one of those 'airmanship' decisions if the NDB is U/S.
