  Log:
  Migrate from setting a CARD_OK flag in a shared word, to setting its
  own entry in the softc.  This should allow more of cbb_pci_intr() to
  migrate to a new cbb_pci_filt() so that we don't have to run cbb's ISR
  in almost every case we get an interrupt.  We can't just move
  cbb_pci_intr into cbb_pci_filt because it does things that aren't safe
  to do from a fast interrupt handler, err I mean from a filter.  This is
  an important first step.
  
  # I wonder if I need to make cardok volatile or not.
