The new 2.6 kernels do not "include ide-scsi", they don't use scsi at all
unless it is a true scsi device. The 2.6 kernels support ide cdrw drives
natively without the need of the scsi hack. You should be treating the
drives as ide drives not scsi. I generally use a front end (k3b) for cdrecord
which set the parameters automatically but by running "cdrecord dev=help" and
reading the man pages you should be able to use the atapi interface.
Hope this helps
