Emacs is easy to fix.  I installed 19.19 with your (Charles Hannum's)
patches, and all I needed to do to get the Alt key to work with pccons
was to put the following in /usr/local/lib/emacs/site-lisp/default.el:

(set-input-mode nil nil t)

The above should work for any Emacs 19.  It won't work for Emacs 18,
but I would expect that few NetBSD users are using v18.

I do not have X installed, but my kernel does have X support compiled
in (XSERVER, UCONSOLE).
