I'm not experienced with 64-bit systems, or SUSE, but if it's a generic
X or fglrx configuration problem I might be able to help. Not without
info, though. What's not working? Can you post any error mesages?
Look at /var/log/Xorg.0.log* for X errors, and grep for "fglrx" in
/var/log/messages to find any errors reported by the kernel module.
Are you sure you have the proper version of fglrx? You need the driver
written specifically for 64-bit systems, and for your version of X. Is
is an official SUSE package, or the installer from ATI, or??? Did you
run "fglrxconfig" after installing?
Also, you might try posting on the Rage3d Linux drivers forum. You'll
surely be seen by some SUSE 64-bit users there:

Oh... and here's a page that may help:
