Greetings DX/XNA board, I bring questions from beyond!

I'm a bit confused as of late over triple buffering in DirectX 9. I've heard a lot of conflicting information and honestly, I just don't know what to make of it.

I want to allow for triple buffering for my projects, but I'm not sure how to go about setting it up?

I've heard that you set the BackBufferCount to 2 (I'm not sure if it needs a specific SwapEffect, or if VSync needs to be on?), and DirectX is supposed to handle it, but I've also heard that the drivers largely ignore these values? I believe Shawn Hargreaves said this when he was explaining why the parameters were removed from XNA4.

Searching the internet has actually led me rather dry. Anything I've found points me to BackBufferCount.

Does anyone have any info they can share regarding this topic? I'm using SlimDX for the record, so any info regarding triple buffering in DX9 will be useful.
