I suspect it will depend on the card.

Some cheap ones will probably do very little; more expensive ones may go
as far as to emulate full tagged queueing in the card so you only
'think' you are talking to the disk.

I have to emphasise here that I've never *used* a card like this, though
I have had one pass through my hands (but since there was no NetBSD
support for it and it was only a cheap-and-nasty one I didn't hang onto
it).
