The best (and perhaps only) realistic approach is to free the Ultrix
source, and use the mscp framework from there. Then we'd have the DSSI, CI
and everything else supported right away.

I've looked some at it, and if I had some time (and someone more to help
out), I'd do the porting. But until the Ultrix sources are free to use,
this will not become available with NetBSD.
