nForce2 Soundstorm on 5.2.1 Release

Hello,

    I have an Asus A7N8X Deluxe motherboard, which has a nVidia 
Soundstorm audio chipset on it.  However, I can't seem to get this 
chipset to detect in 5.2.1 Release, no matter what I try.  Being 
relatively new to FreeBsd, I don't really know that many ways to go 
about trying to get it to detect.  I was hoping someone out there might 
be able to tell me something to try, or at least confirm for me that 
this chipset doesn't currently have a driver that works, so I can stop 
banging my head against the wall.

Also, on a completely unrelated note, how do you get the mouse scroll 
wheel to work?  I've got a Microsoft Optical mouse(PS/2) and while I can 
use the wheel as a middle button, the scroll function doesn't seem to help.

    Thank you
      Casey
