    When I brought up the issue a few months back, the consensus was to
    use ide-cd, not ide-floppy.

    ide-cd also handles DVD-RAM, which can also handle random writes.

    On 2.4:

    scsi0 : SCSI host adapter emulation for IDE ATAPI devices
      Vendor: FUJITSU Model: M25-MCC3064AP Rev: 0051
      Type: Optical Device ANSI SCSI revision: 02

    And yes, this uses the sd driver.
