But we do that for some controllers anyway so it's not something new.
ata_piix already has list of all the devices it supports, so maybe
it's safe to grab all intel IDE devices from ata_generic?  ata_piix
always has higher priority than ata_generic anyway and if a device
isn't grabbed by ata_piix, we don't lose anything by grabbing it from
ata_generic.

Yeap, that's much better, but I still think it would be better to
avoid such detection magics if possible.

Thanks.
