N points:

0. As well as SCSI support for CD-ROMs and SCSI-generic devices
   You need to turn on ATAPI-to-SCSI "emulation" which is actually in the
   IDE/ATA section of the config interface, not in the SCSI section.

1. Under the hood you're using cdrecord, so the doco you need to read
   is cdrecord's, not xcdroast's.
   
   Read the README.ATAPI that is part of the cdrecord package.

2. You may not need SCSI emulation.  Sufficiently recent versions of
   cdrecord and of your kernel (2.4.20 will do) can talk to ATAPI
   devices directly without requiring the "scsi emulation" driver.

3. You need to tell the ATA device driver not to attach the 
   CD-burner, so that SCSI can claim it instead.   Are you passing
   "hdc=scsi" as a boot parameter to your kernel?  (replace "hdc" with
   name of your cd burner device).

4. What does 
        "cdrecord -scanbus" say?
   What about
        "cdrecord dev=ATAPI -scanbus"?
