Thanks for the help. I ended up using Takashi Iwai's dma_mmap_coherent patch and then added the mmap callback to my driver. So far it seems to be working.

The PowerPC MPC8610 drivers enable mmap support, and it seems to work, but that chip has a coherent MMU. I've never done a definitive test that it works, though. What's the easiest way to test mmap?
If you had issues they'd be fairly obvious in the audio stream.
