It's the megaraid_sas driver but it's not shown on the 
site, so that doesn't bode too well!

Well spotted, I saw this bit of the same page...

... and it says:

Driver name: sata_mv

Summary: Similar to ServerWorks "frodo": per-device queues, full SATA 
control including hotplug.

So I'm a little bit puzzled. Unless it means hotplugging the card itself?!?

Anyway, thanks for the pointers.
