	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...
