Well, some experimentation has produced a partial solution.
Consider the following:
Add a additional network adapter to the CP directory entry, but do not
configure it with yast.
Add a private guest LAN and couple the additional network adapter to it.
Add the 'latd' package and configure it to start early in the boot via
/etc/inittab and announce the VM userid as the LAT service name.
Create a second guest, attach it to the IP network and to the private GLAN.
Load LAT on it too.
Configure port 20000 in /etc/inetd.conf on the second guest to run 'llogin'
with the correct service name.
From outside, telnet to port 20000 on the second guest, and you're in; you can
also safely enable root logins for that tty.
At that point, you get a setup that looks and functions exactly like a serial
console attached to a Cisco terminal server, vi, line editing, the works. If
you need encryption, allow logins to the second guest via ssh and run llogin
manually.
You do lose some of the very early startup messages, but if you incorporate
latd into the initrd, you should have everything you need before anything like
LVM processing starts to run (and where you'd really need a console). It also
seems to survive yast doing stupid things when configuring IP support, and
allows guests to come and go w/o preconfiguring stuff. If you really wanted to,
you could even have latd acquire real terminals if your network guys were
willing to pass DECnet out to a real terminal server.
Brandon, would this serve your purpose? You'd only have to deal with the 3270
if a guest was really, REALLY hosed, beyond any chance of ever getting a shell
anyway.

David, truly amazing! Yeah, that should do just about everything right
there. Sorry I didn't see your post right away. I'm looking forward to
trying this.
Arigato gozaimasu!
