Hi Arnaud (and all),

My I2S audio driver seems to work fine for our icecube-based mpc5200.
It is attached for all the world to smear.  Hardware assumptions are 
included in
the comments.  It assumes a pcm1717 i2s dac running on psc2.
It implements much of the oss and mixer ioctls, volume controls, etc.

It seems to be pretty stable:
I've fixed many interrupt and timing problems of the original and
played many songs for many days with this version of the driver.
