 This issue remains.  This order works:
 
   no ppb*	at pci? 	# PCI-PCI bridges
   no pci*	at ppb?
 
 The opposite order:
 
   no pci*	at ppb?
   no ppb*	at pci? 	# PCI-PCI bridges
 
 causes 'config' to segfault and dump core.
 
 The GENERIC configs for architectures with PCI busses have:
 
   pci*	at ppb?
   ppb*	at pci? 	# PCI-PCI bridges
 
 so just prepending "no " to these attachments will result in 'config'
 segfaulting.  The order needs to be reversed when eliding these
 attachments for machines w/o p2p bridges (like original iMac).
