Yes, the ATI RF Remote. It sells as part of the 8500DV Card. Or you can buy it seperately for around US$50 or so. However, it's kinda hard to find from what I can tell.
If you decide to get it (or anything else for that matter) get a program called uIce from

It enables you to use the remote outside the limitations of the ATI program. It's shareware, but well worth the $20. Without it, there's not a whole lot of customisation you can do, but with it, every button is programmable.
The remote is a Radio Freq type. The receiever is a little box with a wire hanging out of it, that (in my case) is on the floor behind my computer. From my testing, the remote works about a max of 15 - 20 feet away (even through walls). It's a bit large, and has a ton of buttons on it, but you can also control your mouse fairly easy with it if you want.

Am I sounding like a saleman yet?
Here's a review:

With the exception of the price, it's really a nice remote.
I use mine for WinAmp and WinDVD and it works flawlessly (with uIce).
