If your kernel uses modular IDE drivers and an initrd/initramfs that loads 
them, your result is the expected one (i.e.: not a bug). One should add the 
following or similar options into /etc/modprobe.conf in the initrd in order 
to get the result:

options ide_core options="ide0=noprobe hda=noprobe hdb=noprobe"

If you don't use initrd, or have a non-modular IDE driver, please ignore 
this message.
