The kernel needs the option because ide-cd is initialized at boot (not during module load). Therefore it will 'claim' the cdburner for itself unless preempted by a command line argument. If however ide-cd is a module, it can either be not loaded, or rmmod'd, and the subsequent loading of ide-scsi can claim the cdburner without the need of "hdx=ide-scsi". I haven't looked into the issue comprehensively, such as how with modules, to get one device working with one driver, and another with the other. I did try for a while just nuking the ide-cd driver, but it seemed like the ide-scsi(and sr_mod) did not work as well across the board with all cdroms as well as the ide-cd driver. -dmc
