I didn't / won't try to read it all, but I think I found some of your
confusion in what I did read (the text you wrote.)

The 'append="hdc=ide-scsi"' does NOT load SCSI drivers. "modprobe
ide-scsi" does that. The append only tells the kernel, "Hey kernel,
please don't let your mean old ide-cdrom driver grab my precious CD-RW
drive, because I would like to use it as a burner."

I haven't tried this yet, but I believe that if ide-cdrom is not built
into the kernel ("M" or "N"), the append line is unnecessary. (Can
anyone confirm or refute that?)

The kernel message for sr0 in a modular kernel comes when the SCSI bus
(virtual SCSI in the case of ide-scsi) is scanned. If kmod is enabled
(which it is in Slackware kernels) it sees all the devices on the bus
and loads their drivers.

It does not.

No, but I'm going to try to help YOU understand. Something else DID
happen. You can prove this to yourself by "removepkg kernel-source" and
rebooting. If no sr0 in dmesg, try "modprobe ide-scsi" and check again.

It IS possible (conceivable anyway) that something related to the
kernel-source package prevented / enabled the loading of your ide-scsi
module. But are you sure you didn't edit /etc/rc.d/rc.modules or
/etc/modules.conf inbetween these attempts? That seems a more likely
explanation.

Armed with better understanding, you can figure this out, if it really
matters to you.
