Well what we are talking about is the presence of CONFIG_PCI=y which even
in Jons case will be true as he wants to run the same kernel on both
sets of hardware.

Now the architecture has PCI support I think its safe to remove the make
PCI optional part of the patch as this should be handled runtime not
compile time.
