I have a fujitsu laptop with:

IC25N030ATCS04-0 ibm 30gb ide drive

ide dvd/cdrw drive using ide-scsi driver:

cat /proc/scsi/scsi:
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
    Vendor: TOSHIBA  Model: DVD-ROM SD-R2212 Rev: 1F15
    Type:   CD-ROM                           ANSI SCSI revision: 02

hdparm is not present on disk, so I suppose hd parameters are not 
changed by rc scripts...
