I don't know about OFED, but I've tried various things on 64KB PAGE_SIZE
systems and it seems to work.  It wouldn't surprise me if there are
issues since the drivers and firmware gets a lot less testing in such
situations but it "should work" -- I'd be happy to help debug if anyone
has concrete problems.
