Hot-swap support with ATA_CAM on ICH9

[Boris Kochergin]

Ahoy. I have a machine with some SATA disks connected to an ICH9 
controller. The BIOS has no options to enable AHCI support on the 
controller (not that I know for sure that it even has AHCI support). 
Once a disk on the controller is removed, using the old ata(4) driver, 
no new disks are detected using atacontrol's "reinit" or "detach" and 
the machine must be rebooted for the new disk to be seen. I'm wondering 
whether this has a chance of working with the new ATA_CAM code. If so, 
I'll give it a whirl and report back. Thank you.
