Hi!!
If you have an FTP client, You can find the RPM on Suse FTP Server (ftp.suse.com)
You are going to find them in :
/pub/suse/i386/supplementary/GNOME2/update_for_9.0
I have to say that I tried to install Suse 9.0 without Gnome or KDE and tried to installed gnome from scratch with those RPMs and it never worked...but I'm a
too...
I hope you succeed to make it works
Good Luck
