I'd still be able to patch the firmware to make the drive hand back a
fake bootable image which hacked the box before Linux ever ran (assuming
the CD drive was in the boot order)
The right answer is to have patches to let HAL update the command table
according to the drive identity. So far nobody has considered it
important enough to produce some (that I've seen anyway).

You might want to combine that with role based security or SELinux rules
