What is missing here is a line like
   Detected scsi CD-ROM sr0 at scsi...

You presumably do not have SCSI CD-ROM compiled in the kernel.
Maybe you have it as a module ?  In the latter case,

no, unless the driver is in the kernel.

insmod sr_mod  # verify you have sr_mod.o in your /lib/modules/VERSION/scsi/
               # since normally, with a standard /etc/conf.modules, sr should
               # be dynamically loaded by kerneld (2.0.x) or kmod (2.2.x)
               # when /dev/scd0 is accessed. Maybe you simply do not have
               # kmod or kerneld enabled and launched
