This is way more complicated than necessary. You do not need to
recompile or reinstall the kernel to update your ALSA modules.
1. Compile the kernel with these settings:
CONFIG_SOUND=y
# CONFIG_SND is not set
# CONFIG_SOUND_PRIME is not set
For menuconfig users that's Sound card support -> Y, ALSA and OSS
support both N.
2. Check out ALSA cvs sources, using 'cvs co .', once your CVSROOT is
set correctly.
3. Run './build prep'. This generates the ./configure scripts.
4. cd to alsa-driver
5. Run ./configure --with-cards=atiixp, make, make install.
That is all. You do not have to touch your kernel source tree at all.
