The thing I don't understand is the ordering in the last line, yet every
example I've ever seen online is like this. I'm tempted to flip it one
day just to see what happens.
When ide-cd gets loaded, you should see the message
ide-cd: ignoring drive hdb
If you don't, then ide-scsi is not going to work.

I do see it, but it's too late... it's coming after hdb is already
identified. The CDRW should be identified immediately after scsi1 as a
device on scsi1, should it not? That's how my SCSI HD is identified on
scsi0 and my scanner when it is attached and on for scsi2.
