Novell's new SuSE page is a little confusing, but it is still there.
I don't know what the mini-installation.iso is. If you want to install 9.2 ftp version, then just hold off a little bit. Last I saw it was projected to be available mid January.
You can currently get 9.1 personal iso, or professional ftp version boot.iso from the official mirrors:
