Is this a matter of finding the right module? The machine is sid,

Maybe you don't have the (new?) ide-cd part built in or the module 
(ide-cd.ko) isn't loaded?
Did you disable ide-scsi emulation?

Just hit this problem myself.  Here's what I did - let me know if it 
works:

1) Remove any hdc=ide-scsi lines from /etc/lilo.conf (grub? No 
idea...) and then run lilo as root.

2) # modprobe ide-cd

3) $ cdrecord dev=ATA -scanbus

... and use the x,y,z triple that cdrecord reports, as in

$ cdrecord dev=ATA:x,y,z other_options

HTH,

Thanks for this and other suggestions.  I had to also modprobe
ide-generic, after a bit of trial and error.  All works now (and I've
somewhat documented it at
http://survivor.sarovar.org/Dell_Optiplex.html.)
