Jeff,

Tejun Heo is one of the main Linux sata driver developers adding
hotswap support.  (He works for SUSE/Novell).

In particular for software mirroring I would want hotswap / dm to be
working as well as they can.  Therefore I would follow Tejun's advice:

I primarily work on sil controllers and ICH7R piix/ahci because I have
access to the hardware and docs.  So, those tend to get new features
first and get a lot of testing.

If you're planning on using Port Multiplier, sil3124/32 would be the
best bet ATM.

I think the ICH7R chips are normally used on motherboards, but the sil
controllers are normally add-in cards.
