Hallo Martin
Your logfile ends when it should start loading glx. Is everything
properly installed?
For setting up XF86Config consult the SuSE database
http://sdb.suse.de/sdb/de/html/wessels_sax247.html
Be modest start with some lower resolution and disable agp
by using: Option "NvAGP" "0" in Section Device.
Only the 2.6x kernel series can handle the modern agp-protocol.
If/when things start working enable the built in agpgart if you
use a 2.4.x kernel.
Good luck
