Perhaps it's a bug?!

I had exactly the same problem as you; but after change the Hardware 
installation as follows it works very well:

=========================================================
** ** Install and setup


** All before:

IDE0: master: Harddisk (/dev/hda<n>)
      slave:  CDROM    (/dev/hdb)
IDE1: master: <no device>
      slave:  <no device>


** After install / kernel config for ide-scsi emulation:

New installation:

IDE0: master: Harddisk (/dev/hda<n>)
      slave:  CDROM    (/dev/hdb)
IDE1: master: CDRW     (/dev/scd0)
      slave:  <no device>


** Cook a new kernel

SCSI emulation

Will man mit einem IDE-Brenner unter Linux was anfangen, wird man um
SCSI emulation nicht herumkommen. Dazu mu� man den Kernel mit einigen
SCSI-Optionen rekompilieren. Folgende Kernel-Optionen sind dazu
notwendig:
[n] Include IDE/ATAPI CDROM support (unter Block devices)
[y] SCSI emulation support          (unter Block devices)
[y] SCSI support                    (unter SCSI support)
[y] SCSI CD-ROM support             (unter SCSI support)
[y] SCSI generic support            (unter SCSI support)

Dabei bedeutet [y], das direkt in den Kernel einkompiliert wird -
nicht etwa als Modul! Schaltet man den ATAPI CDROM support nicht mit
[n] aus, wird die ganze SCSI-Emulation nicht funktionieren.
Ist der Kernel an seinem Platz und war der Neustart erfolgreich, sind
in etwa folgende SCSI-Meldungen zu sehen:

Ebenso sollte die Ausgabe von �cdrecord -scanbus� nun alle korrekt
installierten CD-ROMs und CD-Writer anzeigen.
[NOTE: Das scheint bei der Installation von Michael Mustun nicht 
zu funktionieren?!]
Diese Ger�te werden nun
als SCSI-Ger�te (/dev/scd0, /dev/scd1) angesehen, also nicht 
vergessen /dev/cdrom neu zu linken.

Hmmm...but which IDE device should be emulated?
We should be able to tell (set) this!

Which IDE-Device is ide-scsi emulation?
NOTE: The following does _not_ seems to work (don't know why):
      lilo: append="mem=128M hdc=ide-scsi"


--> So, change the Hardware!!!


** After changed the Hardware:

IDE0: master: Harddisk (/dev/hda<n>)
      slave:  <none>
IDE1: master: CDRW     (/dev/scd0)
      slave:  CDROM    (/dev/scd1)

All works find, even if cdrecord -scanbus reports only the first
ide-scsi device, the CD Writer.
