Note USE_XF86_4 is optionally set to "yes" only for specific platforms
in /usr/share/mk/ -- i.e. on a netbsd-1-6 system the old
xsrc/xc tree will be used when building xsrc on an alpha, by default,
instead of the new xfree/xc tree because USE_XF86_4 is not set for alpha
for NetBSD-1.6.x.

Hopefully someone is working on fixing this problem.  It should be
possible to add wscons support to any X11 server, though I've no idea
what level of difficulty this would be for XDecNetBSD.

I don't think that's exactly true.  Note there is a "tga" driver for the
XFree86 version of the Xserver, though I suspect it can currently only
be used with PCI-attached TGA cards:


There are also some drivers for quite a few other non-VGA-compat cards
in the drivers directory (e.g. for the various Sun framebuffers).
