http://linux.yyz.us/sata/sata-status.html claims that ICH6 doesn't
support hotswap. The Intel docs seem to say the same thing. Pulling the
drive out generates an ACPI interrupt but not a PCI one. I'm really
happy to be wrong here, it's just that everything I've been able to find
so far suggests that ACPI is the only way to get a notification that the
drive has gone missing :)
