game crashes after intro

[Capitán Centollo]

I have purchased the game just after finishing the demo, and when i start a new game it crashes after the intro.

The game version is 1.0.679

I'm using Ubuntu Gutsy Gibbon amd64, i have an ATI X1900XT 512Mb and the latest drivers (8.42.3) and i have installed all the needed 32 libraries and made the .asoundrc file for solving the crackly sound problem.

this is the game output after crash:

Segmentation fault (core dumped)
Penumbra exited unexpectedly, please check
/home/javier/.frictionalgames/Penumbra Overture/Episode1/hpl.log
for any error messages
Also try running
ulimit -c unlimited
And re-running Penumbra and try and recreate the error
then submit the generated core file or stack trace

Here is my hpl.log: [attachment=364]

This is the output of the command ldd penumbra.bin: [attachment=365]

And this is my xorg.conf file: [attachment=366]

Can you help me, please?
