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.
