    Did you re-compile your boot blocks appropriately afterward? cd /sys/boot
    && make all install clean is the ugly way of doing it (I could never get
    the "right" way from the docs to work) and it works beautifully. I have a
    large number of deployed servers using com2 at 38400 for console all the
    way through boot. Make sure you create /boot.config with the correct
    flag(s), too - "-P" if you want it to autodetect keyboard vs. serial
    console on boot.
