Some time has obviously passed, but I have just put telnet and some other stuff on my empeg.

Like jdandrea I have no serial port on my Mac G4, so used FTP to place the files in the appropriate places and then used SITE EXEC via FTP (client = Transmit btw) to run devs and then telnetd, no serial connection therefore required.

I read that some hijack releases had problems with SITE EXEC, but 4.17 worked for me with this and other execs I tried. Maybe Mark fixed it.
