    I'm still running 2.4 on this box, with a combi drive as the primary
    slave. That shows twice too, as

    hdb: HL-DT-ST RW/DVD GCC-4320B, ATAPI CD/DVD-ROM drive

    and then _many_ lines later is the second part

    hdb: attached ide-scsi driver.
    scsi1: SCSI host adapter emulation for IDE ATAPI devices
    Vendor: HL-DT-ST Model: RW/DVD GCC-4320B Rev: 1.01
    Type: CD-ROM ANSI SCSI revision: 02

    So I guess all that's happening is that the two parts come together
    when we give up ide-scsi. The error messages look as if the kernel is
    trying to find any partitions, which isn't going to happen without media
    - you should see how many error messages I get from an ATPAI ZIP drive
    in 2.4 when I boot without media, but they're nothing to worry about.
