output of Linux kernel 3.2.23 ring buffer (dmesg)

As j4ni requested on IRC here is the output from `dmesg` from the 915GM

    $ lspci | grep VGA
    00:02.0 VGA compatible controller: Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller (rev 04)

with Linux 3.2.23 and `drm.debug=0xe`. Though the `PIPE A underrun` message
more or less kicked the beginning out. I will repost that too.
