Modid:  2.5.x-xfs:slinx:128293a
linux/arch/i386/kdb/kdba_io.c - 1.18
        - rework the use of config defines a little, we were using the
          wrong one.

linux/drivers/serial/8250.c - 1.4
        - do not stop at the first setup call in setting up kdb console info,
          there is insufficient data in the structure first time through.
