I'm not sure, if hotplug should take care about automatic module loading
for static devices. Currently, only cardbus manager uses the PCI hotplug
routines. I could be wrong, of course.

I just added a simplified support for ALSA kernel code for alsa-lib.
We have '--with-kernel' and '--with-soundbase' options for the configure
script allowing specification of ALSA kernel header files
(linux/include/sound directory). The other packages uses only alsa-lib and
are not dependent on kernel sources.

Documentation for users will be definitely next step in our kernel
integration process, although there are minimal usage differences
(only compilation) with the standalone ALSA distribution.

Already finished.
