 From reading the mail it's a totally reasonable choice to turn off
PCI because there's normal iSeries configs that don't need it.  EMBEDDED
only is for really odd configs whatever that means (a little more than
usual on x86 thanks to Linus).  Note that you can turn PCI off easily
without EMBEDDED on most plattforms, including x86.
