Have you also compiled the scsi-cdrom support in the kernel, or as module?
it should not make a difference, but it can be tried.

Hmm, I really have only "hdd=scsi" and it worked back then:
image=/vmlinuz
label=Linux
read-only
append="hdd=scsi"

I use kernel 2.4.18, and, if I am not mistaken, this was the configuration
I had:
IDE-support, IDE-cdrom and SCSI-emulation support compiled in. Then
SCSI compiled in and SCSI-cdrom as module.
