The i386 BSP has a custom PCI library which probably implements the API 
in <rtems/pci.h> (cpukit/include/rtems/pci.h). It doesn't use the 
libbsd. In general, the i386 BSP needs an update for state of the art 
x86 hardware:

There are lots of areas in the RTEMS documentation that needs to 
improve. This requires someone who works on this and coordination.
