Xorg log

When I update the kernel from version 3.7 to 3.8 or 3.9 on Arch Linux, I experience the following regressions:

- The color depth is low.
- The system freezes on suspend.
- Opacity problems in 3D apps.

It may or may not related to this patch (I haven't tested):

Implement workaround for broken CS tlb on i830/845
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b45305fce5bb1abec263fcff9d81ebecd6306ede

Package versions:

- linux 3.8 and 3.9
- libdrm 2.4.45
- xorg-server 1.14.1
- xf86-video-intel 2.21.9
- mesa 9.1.3

Xorg log file is attached.

The low default color depth is deliberate. You can always override if you prefer.
3D apps is a mesa bug.
The system freeze is bug 64610.
