 New Revision: 238954
 URL: http://svn.freebsd.org/changeset/base/238954
 
 Log:
   Restore the PCI bridge configuration upon resume.
   
   This allows my TI1510 cardbus/PCI bridge to work after a suspend/resume,
   without having to unload/reload the cbb driver.
   
   I've also tested this on stable/9.  I'll MFC it shortly.
