      The latest kernel on kernel.org is 2.4.28 indeed. The debian stable
    choosed kernel 2.4.18 as kernel for woody release. So debian's kernel
    2.4.18 includes security patches for exploits found in kernels 2.4.19,
    .20, etc.

      Kernel 2.4.18 does support highmem, but debian's package is compiled
    without highmem support. So you have two options:

    1st.
    Recompile debian's 2.4.18 kernel with highmem support, keep eye on
    debian-security-announce list and whenever kernel 2.4.18 gets updated
    recompile it.

    2nd.
    use latest kernel from kernel.org compiled with highmem support and
    recompile it whenever security hole is discovered.
