If it's the same cIOS I can't think of any good reason for it to work with one loader and not the other. Once control is handed off to the game the loader should make no difference.
I own the disc for Other M as well and have played it all the way through with d2x v8 with no problems. There are a few bugs in it and one is related to the Ripley fight, though.
