Open export_descr_buildings.txt and search for the precursor level of the "cataphract" building. That one will have a weapon bonus of -1; change it to 0 and you'll have your cats. Dunno if it's save-game compatible though.
I have tried that and it did not work for me (I assume that if I start a new campaign, cataphracts should be available immediately if I build the necessary MIC-level).

I have noticed that there are no "cataphract" precursor buildings in my campaigns, like it was in 0.8, so perhaps this is the problem? I think I have all fixes installed..
