Even r300 docs mention that ecp divider should be set above 175Mhz, though I
guess newer chips are more likely to succeed overclocking the scaler than older
ones (or it could just be in the docs because it was not updated).
Though in your case I guess you could generate a modeline with reduced
blanking, I think even at 72 hz it would be below 175Mhz. I don't think reduced
blanking is actually specified for anything else than 60Hz, but the monitor
might still accept it.
