Just use OSA-ICC (integrated communications controller, TYPE=OSC). It gives you a TN3270 server that, like the Visara box and the old IBM 2074, creates non-sna 3270 devices on that chpid. It can be shared across LPARs. Of course, dedicating hardware (of any flavor) for a telnet server implies that you have sufficient TN3270 traffic to justify the offload or you don't have sufficient CPU capacity to absorb the additional workload.
