I had luck with the following. It removed all of the dmesg's except one:

   $ uname -a
   Linux qotom 3.19.0-49-generic ...

   $ sudo lspci | grep -is vga
   00:02.0 VGA compatible controller: Intel Corporation
   Broadwell-U Integrated Graphics (rev 09)

And then use the "00:02.0":

   $ sudo cat /etc/rc.local
   #!/bin/sh -e
   # ...
   # By default this script does nothing.

   setpci -s 00:02.0 F4.B=30

   exit 0
