It seems I read your mail too quickly.
But if only apps through ssh are slow, why would you suspect video
driver, and not network / ssh speed ?

And why would 3d acceleration make your X-forwarded 2d app slow ?

By the way, you have no 3d-accel at all with nv, just very basic 2d.
And afaik drm does not do anything on its own. It just provides the
core of graphic drivers, like nouveau for instance. nv does not use it
either.
And there is no reason for using nv nowadays, nouveau does better in
every aspect ! and nouveau does rely on drm so you will want to keep
that.

That said you can blacklist whatever you want, just have a look at /etc/rc.conf.
You could also try blacklisting your network driver, I am sure it will
make everything much faster :)
