    The bug is that syslinux incorrectly positions the stack above the
    command line (but not the stack pointer register; hence the kernel patch
    exposing this bug.) So the stack plus command line end up being limited
    to 512 bytes; how much stack gets used depends on the BIOS, so one
    BIOS may use a lot more than another.
