I have the identical setup. I just use "cdwrite -v /dev/scd0" and it works for me (with an adaptec 1542 and a reasonably fast processor, both CDroms are on the same scsi bus).
Generally, if your SCSI bus is clean, it will write clean. I knew someone who kept trying to load his system to the point that console switches were taking several seconds, but the CD wrote properly.
