IDE HD isn't available when ata.ko module is loaded

I removed device ata from the kernel config file. Now kldload ata doesn't cause IDE disk to come online as I expected. What else is needed for IDE disk to become visible after ata.ko is loaded?

My original motivation for this is that I wanted to attach an older IDE drive to the system, but when ata() is built into kernel it becomes first drive and changes drive numbers which I don't want. But with ata() as a kernel module IDE disk doesn't show up at all.
 
Loading the module manually is not a good way to avoid the drive numbers changing. It might help to do a camcontrol rescan all after loading the module.

An easier and more general-purpose solution is to use partition or filesystem labels, so the drive numbers don't matter.
 
Device IDs shouldn't move around. The GENERIC kernel is built with ATA_STATIC_ID set.
