Well, actually I'm playing with my own driver. Like the Alsa driver
it can do playback on DAC2, which seems to be much easier due to
less backward compatibility braindamage.

I'm now stuck at getting recording to work, since the DMA mask bit
of the Audio1 DDMA controller seems to be stuck at 1, writing
0 to it doesn't change anything 8-(

I remember having had problems with the DDMA controller in the
SonicVibes also 8-(

These are the manuals I have too...

I've put my code on www.ife.ee.ethz.ch/~sailer/esssolo1.c
if anyone wants to play with it...
