console client no workee

[Roland McGrath]

So I've dusted off my Hurd installation and updated with the current
debian+alpha packages using apt-get.  I'm booting the gnumach v1 kernel
from the debian package.  I've done appropriate MAKEDEVs, and diddled
/etc/ttys to try out the nifty console.

hurd:~# console -d ncursesw /dev/vcs/1
console: Console library initialization failed: Operation not supported

What gives?  That is in a telnet session, but trying with -d's for the
hardware drivers on the PC console fails the same way.
