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.
