It seems so. If you're not using initrd, you might want to compile in
the via82cxxx driver (i.e., not as a module), otherwise the kernel can't
read it from the disk. That works great here :)

Just remember to recompile your kernel with IDE generic support (or,
alternatively, use initrd to load the IDE modules) if, in the future,
you change to a non-VIA IDE controller.
