There was a problem around 2.6.12 days as far as I remember where a bad
initrd tool generated initrd images which loaded ide-scsi, and once that
is done the initrd tool will make future ones to match your setup.  I
think 2.6.15 kernel will force it to not use ide-scsi at all, but I am
not sure.

Perhaps just adding ide-cd to the list of modules to load first
explicitly in the initrd tool config will make it do the right thing if
you then regenerate the initrd.
