I correct myself: the freeze happens always, also with small files.

Seems this codec was not found. The OF structure on my PowerBook looks like
this:

ff98be28:       /i2c@18000
ff98ca00:         /i2c-bus@0
ff98cbc8:           /codec@6a

So there are two problem in deq.c:
1. The node is called "codec" instead of "deq".
2. There is no "i2c-address" property.

I hacked that in to make deq attach:

But still no difference. The system freezes when writing to /dev/audio. :(
