    Kudos! I have to leave a real review of the patches to others more
    qualified than me, but where the previous patch set raised all sorts of
    questions for me, this just looks logical.

    I conclude the following from reading the patches:
    - a HPA is always at the end of a disk, correct?
    - the only case where a user should notice a change after switching
    to 2.6.30 is if he has a partition that starts on or after the
    start of the HPA: such a partition will be ignored (with warning
    in dmesg); I guess that is reasonable as at least it will prevent
    "broken" partitions and is probably relatively uncommon.

    Thanks for your continued work on this Bart.

    Cheers,
    FJP
