This isn't a problem with the drive and multiple-lun probing, but rather a problem with the hard-wiring code. The problem is that the hard-wiring code evidently can't deal with multiple peripheral drivers wired to the same bus/target/lun. A work-around here would be to not hard-wire your pass devices, and just hard-wire your CDROM devices.
