Efika (mpc5200b): sound doesn't build/work from linux-2.6.38.x

[acrux]

board: Genesi Efika (MPC5200B)
problem: unable to use sound subsystem instead it works fine with linux-2.6.36.4 (+ device tree supplement, attached) .

With linux-2.6.38.8 and linux-2.6.39.4 it doesn't build.
That's from my build log:

With linux-3.0.18, linux-3.1.10 and linux-3.2.2 it builds but doesn't work.
That's from my dmesg:

[...]
asoc: error - multiple DAI f0002200.sound registered with no name
mpc5200-psc-ac97 f0002200.sound: Failed to register DAI
