This is how I replace the alsa stuff in the kernel source:

1. checkout the "alsa-kernel" module from the alsa-project cvs. Go to 
http://alsa-project.org/download.php for instructions.

2. cd into the kernel tld

3. move  the sound/oss dir to some safe location

4. remove the "sound" directory

5. copy the checked out "alsa-kernel" dir into the kernel tld and rename 
it "sound"

6. remove "sound/oss" directory

7. move  the "oss" dir from step 3 back into the "sound" dir

8. remove include/sound

9. move sound/include dir into the include dir.

10. unless I missed something you can now build and install kernel as usual.
