Hi guys,
I am yet to try this but this might work:
https://github.com/Fsmv/MineOSCrux-Fork
In the description he says that he added tekkit support, but as I stated earlier, I can't confirm it, yet.
Hope it works! And i'm afraid i can't help you chem_fun, sorry.
I'll confirm it when I get the oppertunity to try it out.
