From searching mailing list archives, reading manpages, and grepping
   kernel sources, it appears that NetBSD 1.5.2 on SPARC does not support
   virtual consoles, or wscons at all. Is this true? If so, when is it
   slated for inclusion? Also if so, then why does the sparc install come
   with wsconsctl and wsconscfg?

that is true.  there is no real date for inclusion, but some people
are apparently working on it.  i will let them update here if they
so desire...  the wscons programs are built on all NetBSD platforms,
even though they are only useful for some of them.  that's simply
the way it is :-)

   Not an especially urgent inquiry, as I've already installed
   screen(1); just rather curious.


you're *really* going to be much better off if you run X11 on the 
sparc console, even if you simply open a single large xterm and
run screen inside that.  the issue is that updating the text
console requires serious CPU, and is as i'm sure you've noticed,
quite slow...  this is basically cuz it's a completely rendered
text console.  X is *much* faster.
