I'm not sure of the criteria, but this is what I'm running:

I added ahci_load="YES" to loader.conf and rebooted. Now I see:
You can add siis_load="YES" to loader.conf for SiI 3124.
Ahh, thank you.
I'm afraid to do that now, before I label my ZFS drives for fear that
the ZFS array will be messed up. But I do plan to do that for the
system after my plan is implemented. Thank you. :)
You may even get hotplug support if you're lucky. :)
I just built a box and gave it a spin with the "old" ata stuff and then
with the "new" (AHCI) stuff. It does perform a bit better and my BIOS
claims it supports hotplug with ahci enabled as well... Still have to
test that.
Well, I don't have anything to support hotplug. All my stuff is
internal.

The frankenbox I'm testing on is a retrofitted 1U (it had a scsi
backplane, now has none).
I am not certain, but I think with 8.1 (which it's running) and all the
cam integration stuff, hotplug is possible. Is a special backplane
required? I seriously don't know... I'm going to give it a shot though.
Oh, you also might get NCQ. Try:
[r...@h21 /tmp]# camcontrol tags ada0
(pass0:ahcich0:0:0:0): device openings: 32
# camcontrol tags ada0
(pass0:siisch2:0:0:0): device openings: 31
resending with this:
ada{0..4} give the above.
# camcontrol tags ada5
(pass5:ahcich0:0:0:0): device openings: 32
That's part of the gmirror array for the OS, along with ad6 which has
similar output.
And again with this output from one of the ZFS drives:
# camcontrol identify ada0
