Redhat compiles sr and scsi into the kernel, so there is no sr_mod and
scsi_mod. And you can't modprobe scsi, again because it is in the
kernel.

Yep, that's correct. Redhat provides ide-scsi as a module.

Good. And you reran /sbin/lilo and rebooted? If so, then after typing
"modprobe ide-scsi", you should try again with "cdrecord -scanbus", and
it should give valid data this time.

Unfortunately, the append command does not actually load ide-scsi,
because apparently append only seems to attach drivers that are compiled
into the kernel. However, it prevents the kernel from attaching the
ide-cd driver, which IS compiled into the kernel. If the ide-cd driver
is allowed to attach to the CDRW, then when the ide-scsi module is
loaded, it won't be able to get ahold of the CDRW drive.

No, you do not need to rebuild the kernel. Note that without rebuilding
the kernel, I don't think the automounter can be made to work - at least
I have not figured it out. The only way I could get the automounter to
work with ide-scsi was to compile ide-scsi into the kernel. But then, I
have decided the automounter is evil, so I don't use it anyhow.
