Emilio (CC-ed) has been working on one, and he pushed out a branch I think. Depending on how much time it would take to implement the audio drivers, I think it'd be a good device to stress test it.

Most drivers are generic I think. Most of the devices really needing DMA don't have mainline drivers at all. That includes display, HDMI and audio.
