If PCI is often used for storage, then that's ok. There are a number of
other platforms where PCIe is only used for wireless networking or
other secondary devices, but they are still built-in because they got
added before it became possible for PCIe host drivers to be loadable
modules. I would like to eventually go through and turn those into
loadable modules, but for the moment it would be good to only add
built-in drivers where this is actually useful.
