Most of the devices I have seen that run telnetd are things like powerstrips, printers, and serial consoles. They usually don't have a lot of CPU/random noise and so require keys to be uploaded somehow for SSL/SSH to work properly. If they use the same or related telnetd.. then the fixes are going to be a LOT harder to get out.

2012 the year of the powerstrip worm.

ssh with a predictable host key is still better than telnet. Heck, even ssh without encryption (older versions supported a 'none' cipher) is better than telnet, though on any CPU made in the last 15 years encryption won't be much of a burden.
