Whoever distributes the musix kernel is required to provide the sources,
otherwise they would be in violation of the GPL. Most probably they will
also provide headers for their compiled kernels, but the Debian user
list is not a good place to find someone who knows where the musix
sources and headers can be found. Also, I would expect that building the
vboxdrv module with module-assistant works better with a Debian kernel.

This information might be given in the release notes of Etch+1/2 or in
the upstream information for kernel 2.6.24. If you cannot find anything
there then you can download the common linux-headers package for 2.6.24
and extract include/sound/version.h:
$ aptitude download '~n^linux-headers-2.6.24.*-common$'
$ ar p linux-headers-2.6.24-*-common* data.tar.gz | tar -zxO --wildcards "*include/sound/version.h"
/* include/version.h. Generated by alsa/ksync script. */
#define CONFIG_SND_VERSION "1.0.15"
#define CONFIG_SND_DATE " (Tue Nov 20 19:16:42 2007 UTC)"
Unfortunately, Etch+1/2 only has ALSA 1.0.15.

Linux images for kernel 2.6.26 (which has ALSA 1.0.16) are available in
etch-backports. The virtualbox-ose-* packages are also included in the
backports, so it should be possible to build the vboxdrv module for the
2.6.26-bpo kernel using module-assistant.
