Actually, that was a very useful suggestion :-)

While the alsa driver appears to be derived from the Linux driver I was
looking at before, it does now have DMA support. (emupcm.c)

Creative had told me they weren't going to give that information out,
but it seems alsa has it, so now I can go back to the original DMA design.
