* The namespaces for pcidata and scanpci clash, so both modules can't be

* loaded at the same time. The X server should only load the scanpci module
|
|
* when run with the '-scanpci' flag. The main difference between the
|
|
* two modules is size. pcidata only holds the subset of data that is
|
|
* "interesting" to the X server. "Interesting" is determined by the
|
|
* PCI_VENDOR_* defines in ../common/xf86PciInfo.h.
