Installing that library has solved the textures and bitmaps corruption problem, thanks! However, the GPU still hangs as mentionned in dmesg.
I tried getting a dump, but I couldn't find intel_reg_dumper in intel-gpu-tools-1.0.2, I only found intel_gpu_dump. However, it doesn't work as a user, and it hangs the machine as root, forcing me to reboot (I tried intel_gpu_dump > gpu_dump as root, and the machine becomes completely unresponsive).
The GPU reset function will probably mean that you won't get a meaningful dump with that kernel anyway. The best way is to retry with git master of Mesa, and the latest rc of 2.6.34.
If the hang is still there, grab a dump with intel_error_decode.
(At least this is what I usually do.)
I couldn't find driconf, and I don't know where to put force_s3tc_enable=true; however, since installing libtxc_dxtn worked, I guess it isn't mandatory?
No, shouldn't be necessary if the lib is used.
