Unable to initialize display

[polypolyman]

I've been searching through a number of related threads, the answers to none of which actually helped me.

Penumbra Overture (from the humble indie bundle) worked the first time it ran, but at the wrong resolution (my LCD monitor is REALLY picky about resolution). I set it up to use 1920x1080 fullscreen, tried to restart it and... nothing.

hpl.log ends in:

Initializing Graphics Module
--------------------------------------------------------
Init low level graphics
Setting video mode: 1920 x 1080 - 32 bpp
ERROR: Could not set display mode setting a lower one!
FATAL ERROR: Unable to initialize display!

My display is already at this resolution, just btw.

I'm on gentoo, using a 2.6.33-series kernel, git mesa and libdrm (from a few weeks ago), xorg-server 1.8.0, and the radeon_ucode package - using the open-source radeon driver for my hd4830. This setup works for other games (all the other games in the bundle, games like nexuiz, neverball, etc.).

Output of my glxinfo (cutting out the huge list of Visuals):

Any idea what's wrong and how to fix it?

Thanks in advance.

Odds are is it something with the open source drivers that is causing you issues. Also do realize that Penumbra is a little more graphics intensive than the other games in the bundle, as we heavily use shaders in the rendering pipeline.
