The CD-Writing-HOWTO has a good description of the procedure used for
ide-scsi emulation.
I have the following in my .config (kernel 2.2.17):
CONFIG_BLK_DEV_IDESCSI=m
CONFIG_SCSI=y
My /etc/modules contains ide-scsi so that the module gets loaded at
boot. Per the HOWTO I also set CONFIG_BLK_DEV_IDECD=m, but since I
don't use that mode, it probably could have been turned off and
ide-scsi support compiled into the kernel instead of as a module. I
have a symbolic link /dev/cdrom -> /dev/scd0, as well.
