I don't think the 400K drives will work on the SmartPort. Then again, I don't think they'll work on the Superdrive card either. IIRC, only third-party controllers supported them. The technical issue with the 400K drive is that they need a PWM motor speed signal which the Mac hardware generated. Unidisks, 800K drives, Apple 3.5 drives, and Superdrives generate their motor speed control internally.
I've never tried it but I'm guessing that hooking the 400k mecanism to a daisy-chain card might work. But that wouldn't make much sense since you'd need to rip the daisy-chain card out of an 800k drive. Wayne
