Someone's already gotten it working, if they're watching I'm sure they'll
pipe up on what driver it uses.

Nope, cables are standardized.  I'm not sure what your definition of
"expensive" is but I believe they were roughly 15$ for a SAS>>4sata ports.

I know it supports hotplug and NCQ.  Can't say smartctl was ever on my list
of important features so I haven't bothered to research if it does.  I'm
also not sure what good port multipliers are going to do you in this
instance... the cables it uses already support 4 SATA drives per physical
card port.
