    Yes, I see that this area (which used to be empty_zero_page)
    is independent since 2.6.5.

    So, maybe your patch is correct.

    [Still, the patch brings knowledge about boot_params that earlier was
    concentrated in head.S, setup.c, setup.h to elsewhere in the kernel. Ach.]

    The doc file is still called zero-page.txt. One might add

    0x228 4 bytes command line buffer

    and possibly rename it.
