Well, I'm not the brightest star in the sky, but I found two solutions for this annoyance.
After searching Google for some time, I stumbled across a reference to a file named rc.scanluns, which Wolvix places in the /etc/rc.d directory.
First solution: I moved the rc.scanluns script to a pen drive, and rebooted. The result:
rmb wolvix ~ $ cat /proc/scsi/scsi
Attached devices:
Host: scsi2 Channel: 00 Id: 00 Lun: 00
Vendor: TOSHIBA Model: DVD-ROM SD-R2312 Rev: 1707
Type: CD-ROM ANSI SCSI revision: 00
After reading the script I found the second solution. One of the comments in the script said:
#Run this only if "noscanluns" was NOT given as a kernel option.
So I added "noscanluns" as a kernel option and rebooted with same result.
I don't know how important the rc.scanluns script is (SLAX doesn't use it), but I decided to be safe and keep the script and use the "noscanluns" option.
