    Hello everyone,

    I'd like to present my 7.0-CURRENT XBOX patches. If you put 'options
    XBOX' in your kernel after applying this patch, you will get a kernel
    that is bootable on both ordinary i386 PC's as well as XBOX'es. 'device
    xboxfb' is an XBOX-capable frame buffer.

    You can download the patches from
    http://rink.nu/downloads/xbox-patches/xbox-7-current.diff. I hope this
    patch will be committed to the FreeBSD source tree. Let me know any
    suggestions for improvements.

    The XBOX option depends on I686_CPU and will error out if it is not
    supplied. The overall patch is just over 1000 lines, mainly due to the
    framebuffer driver. You will need the most recent CVS version of
    Cromwell [1], as it now fakes FreeBSD boot info so the initial entry
    won't halt the CPU. This removes the patches in the locore.s file.

    For some reason, the kernel will not work fine if you have syscons in your
    kernel. This only affects the XBOX, so either syscons crashes it somehow
    or it gets a higher priority. However, as the current framedriver driver
    needs to be syscon(4)-ized, I intend to port the framebuffer to the VESA
    framework. Assistance on this is very welcome.

    Finally, I am willing to maintain this so future FreeBSD's will run on
    the XBOX without any issues. Work is underway for the nForce ethernet as
    well as an improved syscons(4)-able console driver.

    [1] This is the Linux BIOS for the XBOX; it was patched in order to boot
        FreeBSD correctly.
