    Just FYI:

    It has been reported that while this patch fixes old LILO, and possibly
    some other boot loaders (unknown), it has also broken older versions of
    SYSLINUX: they still boot, but the command line is truncated (exactly
    how much depends on the BIOS, but typical values are around 130 bytes.)

    This is definitely traceable to a bug in SYSLINUX that was already fixed
    in release 3.50 (the current version of SYSLINUX is 3.52).

    I have chosen to leave the patch in mainline, rather than trying yet
    another recipe and hope it doesn't break on some other random
    combination of bootloaders, since:

    a) SYSLINUX is generally easily updated, compared to other bootloaders;
    b) The failure mode is less severe (it still boots.)

    ... however, you may choose to call differently.
