Logs trying to start gdm

No hardware 3D support for  NVIDIA Corporation NV44A [GeForce 6200] (rev a1) when kernel is compiled using gentoo-sources-3.17.0 (and 3.17.1) in x86 architecture.

gdm finally starts with 3D software rendering because no support for hardware 3D acceleration can be activated. 

This video card worked properly with 3D hardaware rendering for gentoo-sources-3.14.x, gentoo-sources-3.15.x and gentoo-sources-3.16.x

I thought that may be I could get somo more information shutting down gdm and starting X from a console using the startx command (in my desktop, this should  start X with icewm). It fails too, and I get the following logs from /var/log/Xorg.1.log:
