    ... in the lilo configuration works fine in the exact same kernels
    you cite. However, the CD install does not have the console changed
    so it will probably not work. The BIOS is never used past the point
    where the OS is physically loaded so it makes no difference
    if you have "serial console capabilities" in the BIOS.

    You can readily make an 'init' that opens a serial port if the
    console failed to open. That's done all the while in embedded
    systems. You just can't get that off a "distribution disk".
