Julian,
The device does not actually show up as a scsi device with a scsi id, it 
simply emulates scsi communications. 

Do you get something like this from dmesg:
dmesg|grep hdg
Kernel command line: ro root=LABEL=/ hdg=ide-scsi
ide_setup: hdg=ide-scsi
    ide3: BM-DMA at 0xd608-0xd60f, BIOS settings: hdg:pio, hdh:pio
hdg: HP CD-Writer+ 7100, ATAPI CD/DVD-ROM drive
hdg: attached ide-scsi driver.

If so, things are fine.
You can also run lsmod and you should see ide-scsi and scsi_mod loaded.
