Even if it is possible to install catalyst 9.3 on a 2.6.29.x kernel, you still need to downgrade your Xorg installation, as well, which is why it's simpler to use an older version of Slackware. I doubt anyone will walk you through installing an older version of Xorg and, even if they did, there's a pretty good chance it still wouldn't work properly.
