I do that as well.
What I do is remove the scsi card module (53c7,8xx in my case) and
reload it again. This is only going to work if the cdrom is the only
scsi device on that card (ie all your other disks are IDE) or you only
have a scanner or zip drive on there as well (unmounted)
so # rmmod 53c7,8xx
   # modprobe 53c7,8xx
