On my system the modules are not autoloading.  An lsmod immediately after a boot
and before any attempt to access the CD-RW drive shows no scsi-related modules
loaded.  An attempt to mount the cd-rw with a "mount /cdrom" command gives the
error
        mount: the kernel does not recognize /dev/cdrom as a block device
            (maybe `insmod driver'?)

Running "cdrecord -scanbus" results in an error that says it cannot open the scsi
driver.

Is there some file to change or process to follow to get the modules loaded
automatically?
