Ah, I was wondering what was causing that.

My tibook's /etc/power/power-local (or whatever its called) is set to switch
the cpu speed on inserting and removal of the AC power.  After a few days I
notice that I can't play music anymore, and that the programs report that
the dsp is in use, whilst there are no actual programs using it, and yes you
can't remove the modules.

So, you are not alone :-)
