do a lspci and identify your video device bus. then put BusID "<bus
id>" in your
device section in the xorg.conf.
example; let's say that my video device has been identified on the
1:5:0 pci bus.
i'd open my xorg.conf and put the following line in my device section.

  BusID         "1:5:0"

after that select that specific device in your screen section so that it can
be used as default for that specific screen that is set as default in the
serverlayout section.

it influences the board you chose.
