Just in case you wish to add a "fix" for the cheaper recipes from that mod, it's Metallurgy. Only base metals, mind you, has this problem(since Base Metals machine is the Crusher, which is basically a IC2 Macerator), the rest of the machines are(as far as I can tell, haven't been able to test the Abstractors yet, due to Prometheum being a right pain to find) completely different then IC2 machines.
I would also request, if you're going to "fix" Metallurgy in that way, could you also add a config option for Metallurgy style IC2 and GregTech ore generation? IE anywhere there is stone, they can spawn(assuming it's not biome locked, anyway, or has a limited chance to spawn in a chunk). Basically full world height ore gen in stone.
I like that bit about Metallurgy almost as much as I like the Mint and the Villagers trading with coins.(also if you're making a Metallurgy patch, maybe add a way to convert IC2 Credits into Metallurgy Coins, and maybe a lossy way to turn them back? I'd be ever so thankful)
