Xorg 7.2 update

All,

I just updated my 6.2 box to the new Xorg 7.2 distro.  I followed all  
the directions in the UPDATING file.  It appears all the directories  
have been properly built.  I also successfully ran the "mergebase.sh"  
script from the Tools/scripts directory.  However, when I try to run  
X, I get the following error:

(EE) Failed to load module "pcidata" (module does not exist), 0)
Fatal server error:
Unable to load required base modules, Exiting....

I've looked around and cannot find any references to a "pcidata"  
module.  Any insights?
