Serveral reasons, there maybe more than one module that does slightly
different things like with sound and scsi, there are loads of scsi and
sound drivers if it's not configured in /etc/conf.modules correctly it
won't know what specific driver it needs.

Not relevent ide-cd is not a module in the supplied kernel it's built in.

It's build in, all ide cd's will be accessable as standard ide devices
(eg. /dev/hdX) untill the ide-scsi module gets loaded. Not all ide cdroms
get along well w/ ide-scsi, you wind uo with funny things like 6 extra
cdrom devices.
