Abubakar pointed out to me that there is an installer for mono 1.0.5 at this location. All you have to do is download that .bin file, copy it to some location on your Linux system, chmod +x the file and then run it. That will launch an installer for mono which does all the dirty work for you.
It was reported working on RH9, Fedora Core 1/2/3, Suse Enteprise 9, Novell Linux Desktop, and Suse Linux 9 in this posting
