I see this message now.

  (II) Loading /usr/X11R6/lib/modules/libpcidata.a I am at 0x186fad8
  (EE) LoadModule: Module pcidata does not have a pcidataModuleData data object.
  (II) UnloadModule: "pcidata"
  (II) Unloading /usr/X11R6/lib/modules/libpcidata.a
  (EE) Failed to load module "pcidata" (invalid module, 0)

  Fatal server error:

I was not found though looked for pcidataModuleData.

  # grep pcidataModuleData  
obj/powerpc/destdir.bebox/usr/X11R6/lib/modules/libpcidata.a

  (on i386)
  # grep pcidataModuleData /usr/X11R6/lib/modules/libpcidata.a
  Binary file /usr/X11R6/lib/modules/libpcidata.a matches


And, I learnt xf86ScanPci.c had pcidataModuleData.  However, it is
necessary to define -DXFree86LOADER as for this.  And, XFree86LOADER
is not defined according to build-log of xf86ScanPci.c.

Is this cause understood?
