The directory <cdrom>/dosutils/autorun should be renamed back to 'autoboot' or BAT file <cdrom>/dosutils/autoboot.bat should be corrected to point to the new name of this directory.
I also encountered this issue but manually ran the loadlin command and after it boots up and detects the CD-ROM drive (CR-563-B SBPCD) it still reverts to the empty driver list under "other CDROMS" from bug #12145.
Fixed for next beta -- thanks for catching this.
