The various IDE modules do not depend on ide-probe, which allows us
to load the probe module, probe the devices, and remove the module
afterwards, when the devices are actually in use.
This has the side effect that we will need kmod for a fully automatic
IDE module loading setup. When kmod is used, the above aliases should
work (the IDE driver requests the probe module if a sub-driver is loaded
and we haven't found any IDE interface yet).
Alternatively, when using kmod with the default "alias block-major-[3,22,...]
ide-probe" setup, the IDE driver will use the media type to request the
appropriate sub-driver (ide-cd, etc) on the first access to /dev/hdx.
If kmod is not used, adding:
modprobe ide-probe
(and an optional rmmod ide-probe)
to the startup scripts will work as well.

ide-proc.o is not a stand-alone module yet (it is linked into ide-mod.o).
