xf86-video-ati: Segmentation fault

[TAXI]

Hi,
I'm running gentoo linux. I installed the demo with this ebuild: http://bugs.gentoo.org/show_bug.cgi?id=336660

I'm using gallium3D, for that I have installed the following ebuilds:
x11-libs/libdrm-2.4.24
media-libx/mesa-9999
x11-base/xorg-server-1.9.4
x11-drivers/xf86-video-ati-6.14.0
sys-kernel/gentoo-sources-2.6.36-r5
dev-libs/libtxc_dxtn-1.0.0-r1 from http://bugs.gentoo.org/show_bug.cgi?id=65607

My problem is that the game crashes at the loading screen (after setting the gamma)
the only output I get:

Code: (Select All)

$ /usr/games/bin/amnesia-tdd-demo
[1] 25001 segmentation fault  /usr/games/bin/amnesia-tdd-demo

Am I missing something or doing something wrong?

P.S. Sorry for my bad english.

//EDIT: My Graphic Card is a RadeonHD 4670 and this system is amd64 (no-mutilib)
