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.

$ xrandr --newmode "1920x1080R"  138.50  1920 1968 2000 2080  1080 1083 1088
1111 +hsync -vsync
$ xrandr --addmode VGA1 1920x1080R
$ xrandr --output VGA1 --mode 1920x1080R
$ xrandr --output VGA1 --mode 1920x1080R --output LVDS1 --off
$ dmesg > 20121004--eeepc-701-4g-VGA-1--mode.dmesg
