Hmm, the DMA problem results in pops in the sound (eg. playback stops),
or stuters.  If you are getting garbled sound, that is likely something
else.  I have a suspicion that we're missing to setup somethign in the
WaveArtist that BIOS would normally do, because from time to time, when
I power up a netwinder, the little three-note chime it plays moments after
powering on comes out all the wrong notes.

Interesting.  I'd recommend building the tulip driver with debugging
enabled (at least, media level debugging) and seeing what the netwinder
thinks.  If its renegotiating parity/speed, you'll see info on the
console and/or in dmesg output.
