It was my fault with the patches: There where unexcepted whitspaces.
With -l  or  --ignore-whitespace it was no problem.

I've patched the mm1-kernel with the patch below only.
The Problem now is anymore a little diferent. I can play sound whit 
cat soundfile > /dev/dsp. But after a few seconds there is this message
in dmesg:

When i start Sound whith xmms (alsa) i can hear sound. But when i stop
xmms, there apears a new message in dmesg:
