A Nouveau port, if it works reliably and supports all the same hardware
as the closed-source drivers, would greatly simplify things for
sysutils/desktop-installer.
I recall reading in a distant thread that the Nouveau developers are
friendly to the idea of a FreeBSD port and the barriers are only
technical. So maybe this is worth some investment if we have someone
with the right skills available.
