The log shows you can use the vesa driver. The nvidia driver fails to load the glx part for some reason, so I'd just make a line Driver "Vesa" in the appropriate device section to have X running and then look what's wrong with nvidia.
But as I already said, I seem apparently incompetent to get X running without xorg.conf on many hardware combinations, so I am looking forward to SirDice's suggestions, too.
