:I created an ISO that added the PCI ID to the interrupt handler for

:away. Here's the patch (note that the ICH6 references are from a
:previous patch).

    Ok.  You submitted a similar patch January 31st.   Joerg was
    going to do something with it back then but must have forgotten :-)

    I'll commit it.  It probably isn't entirely correct but eventually we
    are going to have to bring in the latest ATA driver from FreeBSD anyhow,
    so I am not going to worry about it changes that might not entirely work,
    but wouldn't have worked at all before for those device ID's anyway.
