Bryan,

If I remember correctly, your devices changed.  The IDE CD-ROM device
was linked from something like /dev/hdc to /dev/cdrom.  Now that you
emulated them as SCSI, the CDRW device points to /dev/sr0 or /dev/scd0
(on my RH6.2 system, I point to /dev/sr0).  You need to put in a link
from /dev/sr0 (or scd0) to point to /dev/cdrom.  At that point, it
should work.
