    Did you actually split and send out your patches? :)

    Needs splitting and most of this stuff needs new re-sync with 2.6. :-(

    Now I remember why this wasn't applied.
    It breaks braindamaged HDIO_GETGEO_BIG_RAW ioctl
    (because changes way drive->cyls is calculated).
    We workaround-ed it in 2.6 by removing this ioctl. :)
    I think we really should do the same for 2.4.
