ah, yes, the rm30 is different at the back, outy rather than inny, (absorb the technical vibe there)
Most shimano freehubs will fit from deore upwards.
I've got one of these put away for when the next m750 hub goes bang (known for it)http://www.chainreactioncycles.com/Mode ... elID=88244
the freehub will fit. it may be necessary to experiment with spacer arrangements (like the one that sits behind freehub and hub shell). also if any of your cones are pitted and the new ones match, mores the better. Dust seals may be fine too or reuse your existing ones. like i say, some trial and error but these freehubs are fundamentally the same.
on the link LX565 is listed too.
