Holy shamoley!  That's really bad.

Man, that's weird.  A "make" shouldn't wipe out the currently installed
stuff unless you did a "make install" and the Makefile's dependencies
were screwed up.  If it wiped your stuff out with a "make install" and
the initial make was unsuccessful, then I'd shoot a strongly worded note
to the ALSA people telling them their Makefile is buggered.

As to the source, it should be in /usr/src/linux-kernelversion.  For
that version, /usr/src/linux-2.6.8-1.521.  A "yum -qil packagename"
should tell you what files were installed where.

Oh, and I forgot, you need to call it "yum install kernel-sourcecode*"
for the source to be installed.
