        Well, this has nothing to do with the above, but is there any
        utility or /proc entry that lets me say to my CD drive that it
        should not work at full speed?

        Basically, some drives make way too much noise when they're
        operating at full speed. When I'd like to listen to some MP3s
        from a burned CD-R, what I'm currently doing is copying the
        files that I want to /tmp and listening from there, but this
        is obviously a dirty solution. :-(

        Thanks in advance for any hints, Roger...
