  Log:
  Update the probe some more to deal with 16/32 bit issues. If the chip
  is already in 32-bit mode, we need to be able to detect this and still
  read the chip ID code. Detecting 32-bit mode is actually a little
  tricky, since we want to avoid turning it on accidentally. The easiest
  way to do it is to just try and read the PCI subsystem ID from the
  bus control registers using 16-bit accesses and compare that with the
  value read from PCI config space. If they match, then we know we're in
  16-bit mode, otherwise we assume 32-bit mode.
