Thank you for the help!

Ok, it's attached (and shortened a little) with my Xorg.conf .

It's standard Fedora 4 kernel 2.6.14-1.1656_FC4.
By the way, my GF6600 is PCIe, not AGP.
According to my /usr/src/kernels/2.6.14-1.1656_FC4-x86_64/.config :

CONFIG_AGP=y
CONFIG_AGP_AMD64=y
CONFIG_AGP_INTEL=y
CONFIG_DRM=m
CONFIG_DRM_TDFX=m
CONFIG_DRM_R128=m
CONFIG_DRM_RADEON=m
