  Log:
  o The ricoh bridge needs us to turn off the function interrupts for
    16-bit cards when we're powering them up.  Other bridges may have
    similar issues, so we do this for all of them by setting the
    interrupt in the PCIC register 3 to be 0 (done always anyway)
    and turning on the bit in the bridge control register to route these
    interrupts via the ISA bus (or via the interrupt configured in the
    PCIC register 3).  '0' means disable completely.  There's a small
    chance this may interfere with the o2micro power hacks, but I'll
    wait for reports to come in from o2micro users.
  o Expand some of the comments about why we do certain things.
  
  # this gets rid of the interrupt storm warnings on my 505TS.  I think
  # that we may need to do something similar on suspend, but I'm unsure
  # since I don't have a laptop that supports suspened/resume with a
  # ricoh chipset in it.
