JFTR: You need at least ALSA-1.0.24 userland (or the corresponding hdspm.h respectively) for the new driver (2.6.39 and above). Likewise, if you intend to use hdspmixer, you need the yet unreleased 1.0.24.2 version of alsa-tools, so go for the git version: http://git.alsa-project.org/?p=alsa-tools.git HTH
