From README...
The following drivers support new features.
ata_piix: new EH, irq-pio, warmplug (hardware restriction)
sata_sil: new EH, irq-pio, hotplug
ahci: new EH, irq-pio, NCQ, hotplug
sata_sil24: new EH, irq-pio, NCQ, hotplug, Port Multiplier
^^^^^^^^^^^ ^^^^^^^^^^^^^^^

Yes, there is 4726. I don't have 3726 yet but 4726 is probably 3726 +
storage processor (so that it can do disk virtualization/RAID stuff).
I'll add support for 3726 soon.
PMP support requires support from low-level drivers (sata_sil24,
sata_promise,...) and sata_promise doesn't have it yet. As noted above,
the only supported card is SiI3124/32 and I'm working on AHCI. As for
sata_promise, I don't know. I don't have the card nor the document, so
it won't come out of me. Jeff is planning to work on sata_promise and
he might also do PM stuff, I guess.
