ICH6 and ICH7 support it just fine, through the normal SATA PHY

ICH6 supports it even in non-AHCI mode? You may want to update the

Yes, its a bit outdated. I just found out that ICH6/7 supports access
to SATA PHY registers even in non-AHCI mode.
Further, although one can detect hot-unplug on ICH5, hotplug is probably
not detectable without polling or SMI.
ACPI allows us to detect hotplug on ICH5, which sounds like a good
argument for its inclusion.
One special case (ICH5 hotplug, but not ICH5 hot unplug), when all other
cases are handled in the normal way?
That's not a good argument at all.
