ALSA is built externally from the kernel. Make sure you have linux-headers-lum-2.6.24-16-* installed for your flavour, e.g.,
sudo apt-get install linux-headers-lum-2.6.24-16-generic
If your build environment does not use the kernel Makefile, then you must be sure that /usr/src/linux-headers-lum-2.6.24-16-generic is first in the include path.
