As a general rule of thumb any time the Qsys system changes I would get into a habit of regenerating the preloader. I don't think it'll make a difference here since the preloader doesn't know anything about FPGA DMAs but you don't want to face a hardware + software mismatch getting into a habit of using the same preloader across multiple generated Qsys systems.
