Actually that was the 0th step that I forgot to mention. I'm installing
the headers from the alsa-driver snapshot into /usr/include/sound and
then I build alsa-driver. Then I use the symvers from the alsa-driver
build alltogether with the headers that I've already installed into
/usr/include/sound to build the V4L ones.

Sorry If I understand what you said wrongly.
