  Modified files:
    sys/alpha/pci        cia.c 
  Log:
  On an AS 600 5/266 (and possibly others), accessing the configuration
  space of PCI devices that don't exist cause PCI master & target aborts
  rather than returning ~0 or giving a machine check.  Bring in some code
  from NetBSD to handle this properly.
