Created an attachment (id=49664) --> (https://bugs.freedesktop.org/attachment.cgi?id=49664) dmesg output showing the lock up

I am using the stock kernel in F15 (currently 2.6.38.8-35.fc15). This crash occurs anytime I try to play the game Cogs (part of "the Humble Indie Bundle 3" [1]).

To get the game to run, I had to install a library to provide 'S3TC' support (aka GL_EXT_texture_compression_s3tc). Initially, I installed S2TC [2], but that resulted in a GPU Lockup. I then installed "libtxc_dxtn" from the rpmfusion-free repo, which causes the same GPU lockup.
