Yeah, this is neat. If I watch the console:
hijack: removed menu entry: "Serial Port Assignment"
khttpd: listening on port 80
kftpd: listening on port 21

But, according to nmap (range 1-65535)
Initiating SYN Stealth Scan against 10.254.0.4 at 00:30
Adding open port 21/tcp
Adding open port 8301/tcp
Adding open port 8300/tcp
Adding open port 23/tcp

and none others. khttpd_verbose=1 is useless, of course. I still don't know what the problem is. It stopped working in v340 (it may have worked for a while before stopping) and updating to v344 changed nothing. I have no idea, at this point. I'm about to start looking at code now.
