    SubjectVIA VT610 IDE support for 2.4.28 (trivial)
    hi,

    I found an older version of this patch (against 2.4.22) on some website.
    After a little bit of editing it applied cleanly to 2.4.27 (and now
    2.4.28). It works fine for me on a ASUS P4P800-Deluxe with 4x 300GB disks.

    Maybe someone finds this patch helpful. Any reason why the original
    patch did not make it into the kernel ?
