I didn't see any support for Nforce2 in there....
Also, this setup worked with Gentoo.
  

They spell Nforce2 as CONFIG_BLK_DEV_AMD74XX.  Build it in, because if you merely module it you still have to bother to tell dma to come on in an init script.  After installing this and enabling DMA I got a factor of 23 improvement in IO speed.

Since we're both nforce2 users, maybe we can help eachother in other ways.  Like damned if I can make alsa work.  :P
